The Strategy
My goal this month was the new award, fastest spaceship victory.
The biggest bottleneck in a spaceship victory is research. Production is seldom the problem as by the time it's possible to build the space ship, there are usually several high production cities available.
With this in mind, my strategy revolved mostly around ways of researching as fast as possible. The main points of my strategy are as follows:
- AI Help - This could be the best way to speed up research. The fastest I can research is one technology every four turns. With several viable opponents, it should be possible to get technology quicker than this through trading.
- Optimal Size - My plan was to grow to the optimal number of cities then stop; focusing on research and generating gold for research. Growing beyond the optimal number of cities has diminishing returns and may draw my resources away from research.
- Wonders - Priority wonders are ones that directly help research (i.e. Copernicus's Observatory, Newton's University, Theory of Evolution and SETI Program) then ones that help indirectly (The Pyramids, Hoover Dam, etc). Wonders like The Great Wall and Universal Suffrage are of little value.
- Pre-building Key Items - Key city improvements and wonders should be pre-built as much as possible before the required technology is discovered. This will maximize their value and in the case of wonders, minimize the chance of losing a key wonder. This strategy is especially useful for the last couple of spaceship components. Ideally, the spaceship can be completed the turn after the last required technology is discovered. This strategy makes The Manhattan Project a worthwhile wonder as ICBMs work well for pre-building spaceship components.
Ancient Times
This month was any easy map and an easy level. From the start I had doubts about my primary strategy of getting the AI to help in research. Fat chance on warlord level.
My first focus as usual was founding as many cities as possible. Since my goal was research and it was warlord level, my cities were not built ICS style. I wanted all cities to grow to their maximum potential so they were laid out with minimal overlap.
For the first while most cities produced warriors or settlers. Settler production was timed so a settler was produced as the city hit size 3. The warriors were useful for finding huts and preventing my neighbors from becoming too aggressive.
Throughout this build out process my city count was always around double the Persians and triple the Babylonians. Research at this time wasn't a priority. It was kept at a minimal level for 1 technology every 40 turns and always on the most expensive technology. Several technologies were obtained through trading and 1 was found in a hut.
By the time expansion was nearing completion on the home continent, I had claimed all of the area near the start position and a strip of cities between the Persians and Babylonians. I had also managed to claim spices, ivory and silk.
Middle Ages
I completed the Great Lighthouse wonder around the start of the middle ages and set out in search of the other civilizations. It didn't take long to find the Chinese then buy contact to all others.
Keeping with my strategy, I made sure everyone had contact with everyone else and everyone was on par technologically. I also began doing my own research starting with the most expensive technology. My hope was the AI would research the cheap ones and I'd trade for them.
Through exploration and obtaining maps, I discovered some unclaimed dyes, gems, furs and wines. I was able to claim the gems, dyes and furs but didn't bother with the wines. This gave me 6 luxuries. With luck, I would be able to trade for the other two with the discovery of Magnetism.
I increased my research spending as cash permitted and eventually started researching the cheap technologies. The AI was hardly helping out at all, mostly adding unrequired technologies from the previous age. By the end of this age I was researching a technology every 4 turns.
Due to my quick start, my culture was far higher than everyone else. This resulted in about 4 or 5 cities defecting to me during the course of the game. In most cases, I either refused the city or gave it right back. My empire was right around the optimal number and I didn't want the addition of some poorly developed city on the outskirts of my empire causing empire wide corruption. I later learned this is not how corruption is calculated and should have kept them.
Industrial Ages
This is the age where I gave up dragging the AI along in the tech race. Their research rate was beyond stupid. Any slower and they would be forgetting technologies.
At the start of the age, either the Germans or Babylonians discovered Nationalism. Scientific civilizations get one free advance at the start of each age. Between the 7 of them the only other technologies they discovered in this age were Espionage, Communism and Sanitation and these weren't required technologies.
I was able to discover a technology every four turns throughout this entire age. I made one researching detour to get the unrequired Sanatation technology, but this was needed to continue my research momentum. With hospitals, my cities could grow to their maximum potential increasing my income by about 2/3. The AI's did eventually discover this one but I'm not sure I could have waited. Half way through the industrial age I was barely able to afford to keep the research rate at one technology every four turns. The extra income as a result of hospitals made the difference.
With the discovery of Scientific Method, I began construction of The Theory of Evolution wonder. There was no danger in losing this to one of the AI's as they were several technologies behind. This wonder gives two free advances; the one currently being researched and one other. To maximize the benefit, I timed this wonder to complete one turn after discovering a technology. I also started research on the most expensive technology and set the research level to zero for the one turn while waiting. This gave me a bunch of gold and 2 expensive technologies. I'm not sure what happens first when a wonder is one turn from completion and you are one turn from a discovery. I might have been able to squeeze another turn out of this.
Although I had given up keeping all opponents even in technology, I was selling technologies to the highest bidder. The extra gold was banked for the modern age when technologies got more expensive. I also brought the Germans up to par with me in research towards the end of the age. My reasoning was to trade for the free technology they would get once they hit the modern age.
Around the end of the industrial age, I was becoming concerned that I wouldn't be able to continue to research one technology every four turns in the modern age. I had a considerable amount of gold saved up, but you can only set the research rate to 100%. What I needed was a larger income, even if all of it is lost to corruption.
After reading Alexman's thread on corruption I learned that corruption due to the number of cities depends on the number of cities closer to the capital, not the total number of cities. This means adding cities to the outer part of the empire should have no effect on the core cities. It also means I probably could have a much larger empire and expect a reasonable return from the extra cities.
The obvious way to increase my income was to take out the Babylonians. My military was far superior to theirs both numerically and technologically so the outcome was never in doubt. The Babylonians were destroyed in 2 turns without using any ROP violation tricks. Casualty count: 1 cavalry. This netted me additional 7 cities giving me 30 in total.
I had two elite warriors from barbarian attacks at the beginning of the game so I though I'd take a shot at getting a leader. They had two bowmen standing around so I pounded them down to 1 hp and killed them with the elite warriors. No luck though, I'll likely go the entire game without a leader.
Modern Times
I entered modern times with over 22,000 gold banked. However, upon starting my first modern age research project, I discovered it would take 5 turns at 100% research to learn the cheapest technology. Allot of good that banked gold is doing.
I brought the Germans into the modern age by selling the required technologies to them. They got their free technology, Rocketry, which I could buy outright or trade for once a few discoveries were made.
I managed to bring my research time down to four turns by joining workers to my newly liberated Babylonian cities but the bigger problem remained. This was the cheapest technology and I would have to increase my income substantially to continue this pace.
Time was of the essence, I hoped to complete the game in 37 turns (9 techs * 4 turns + 1 turn for ss). Nearing panic, I considered my options:
- Warfare - I could easily take several cities from the Persians. I wouldn't be able to take all of them quickly as the Persian empire was large. This option had many risks including the possibility of bringing all countries into war, falling into anarchy during the war, production diverted from the spaceship, and the time it takes to develop the new cities. At this point I didn't know where the aluminum or uranium was and I may need to trade for them.
- Rush Expansion - The conquered Babylonian cities were not fully developed and there were a few places in my empire some cities could be squeezed in. My massive bankroll and large production capacity could have these cities fully developed and populated quickly although I'm not sure they could contribute quick enough.
- Computers - This technology gives me the SETI Program wonder and research labs. I had already prebuilt the SETI Program and could complete it within a few turns of the discovery. If I research this technology first and prebuild research labs everywhere I could have research labs in most cities about 5 or
6 turns into the modern age. Since the research rate is at 100%, this would effectively increase my income by 50%. This sounds like a winner.
It was obvious that I had saved way too much gold. With trading, my treasury was still building even with research at 100%. It may start shrinking once the deals expire but it won't likely make a dent in the treasury by the end of the game.
I proceeded to use my saved gold to rush improvements in the conquered Babylonian cities. I also pre-built research labs in most cities in anticipation of the Computers technology. Once it was discovered, I completed the SETI Program wonder and had research labs in most cities the next turn. The added income enabled me to research techs every four turns for the remainder of the game.
To my surprise, the Germans researched a required technology on their own. Perhaps favoring one or two AI opponents is a better approach for getting the AI to do some useful research. From this point on, I gave my technology to the Germans and traded for any they discovered but with only 7 required technologies left they weren't able to help any more.
The only potential glitch came two turns before the last spaceship technology. For no apparent reason, the Zulu's moved a large force within the borders of a remote city of mine. Their intent was obviously hostile and they declared war when I told them to leave. My concern was not for the town, but that the Japanese would be dragged into a war against me as they were supplying aluminum.
I contacted the Japanese and gave them whatever they wanted for an alliance against the Zulus. For good measure, I did the same with everyone else.
Two turns later I discovered the last spaceship and one turn after that my spaceship was launched. The Zulus never did attack, seems they had bigger problems on their other borders. I never fired a shot during this brief late war, as there really was no point.
Throughout this entire game, I was at war for only 5 turns. My only active war was the 2-turn conquest of the Babylonians. As far as I could tell, none of the AIs were at war until the last few turns of the game although the Zulu's must have fought some early battle as their invasion force contained an army of warriors.
Conclusion
This month's game was fun but not too challenging. There was never a question of if I would win, just when. With this map and this level I don't think any strategy would be difficult. However, this was a nice change of pace.
Some improvements on this strategy would be to grab more land at the start and keep most cities won by culture. An early conquest of the Babylonians would have been beneficial. The weaker civilizations do not contribute on any level and if their land is useful it's better off under my rule.
On warlord level, I would have been better off favoring one or two AI opponents and leaving all others in the dust. Having them all equal seemed to translate into them all being equally useless. The only time they added research was at the start of an age and when one of them was ahead of the others. On higher levels, having most or all of the AI opponents on par may be a viable strategy.
A higher difficulty level would add an interesting dynamic to this strategy. You want to keep the AI opponents on par technology-wise so they can contribute while still launching the spaceship before they do. If you leave them behind or milk them too much it costs unrecoverable turns of research. On the other hand, if you keep them at par you run the risk of invasion or losing the space race.
