This was only my 4th Civ4 game. It was also the first game I played on Prince (the other 3 were Noble).
A brief summary with some lessons learned:
I expanded much too quickly. Not with settlers (I only founded 4 cities in the course of the game), but through capturing cities (including those of the barbarians). More on that later.
Incidentally, I didn't realize until part-way through the game that one could capture barbarian cities. I had been stationing units outside the barbarian cities to gain XP and to keep the barbarians away from my cities, but I would have captured a few early on (there were some in very nice locations) had I realized that was possible.
Mistake #1.
As it was, by about 60BC I had 5 cities, but no horsies. Isabella (to my south) had a nicely corralled pasture of fine war-stallions. So I decided to trade. No, not with Isabella. I traded blood for horses. For over five hundred years, I sent young soldiers armed with swords, axes, and bows to beat down the Spanish walls and take what was rightfully mine. Sounds bad, but it was actually quick and merciful in game time. In just a few turns I had captured 4 Spanish cities (including 2 Holy cities, horses, and other resources) and made peace. In the same time, I captured a barbarian city.
This brought me to about 680 AD with 9 cities. Research was low and dropping as I continued to build units to defend my vast borders against rampant barbarians. It would be about 500 years (including several turns of 0% research) before the economy recovered from my over-expansion.
Mistake #2. Surprisingly, I never got too far behind in tech, due to several wars occuring over that span (no, I didn't start
all of them...
) as follows:
960-1110 AD: vs Montezuma
1350 AD: vs Isabella, taking the last Spanish city
1400s: vs Montezuma
1600s: vs Washington
1700-1714: vs Monte...captured his remaining 4 cities in 2 turns
1746-1796: vs Saladin (captured and/or razed 12 cities)
1832-1871: vs Washington (captured and/or razed 8 cities)
1877-1886: vs Saladin (captured his final 3 cities)
At this point I had a pretty good lead in score, territory, and power (I had decided early on to try for a domination victory). I easily had the pop %, but I needed about 6% more territory for the win. Culture expansion was out of the question; my borders were tight with Cyrus and Mansa (the only other remaining civs at this point), and none of my border cities had high culture (having been recently captured). So it was once more into the breach.
Cyrus and Mansa had a defensive pact, which was going to make things more difficult. I wasted a few turns trying to get either one of them annoyed at me enough to attack (thereby breaking the defensive pact), but I quickly tired of that game.
Mistake #3.
I built enough units (tanks and bombers, mainly) for 3 invasion forces plus the defense of my border cities. The war to end all wars (1896-1905) resulted in the capture of 13 cities (most from Cyrus). I needed about half of those to put me over the 64% territory criteria for the domination win.
Domination, 1906
5607 in-game score, 21740 total score.
Misc:
1) I enjoyed playing on Epic. The games on normal setting always tend to be tech races for me, without many chances for a bloody war. This was the first game in which I got in large-scale wars.
2) The AI seemed, well, a pushover. Maybe I got lucky, but this was only my 4th game and I never felt in danger of losing, despite making many mistakes. The only cities I lost were border cities, taken a turn or two after I had captured them. I played overly-cautious, thinking that at any moment one of the AIs was going to put the smack-down on me, and it never happened. Had I known, I would've played more aggressively, in which case I may have finished much earlier. I'm hoping to see even higher difficulty levels in at least some of the future GOTMs.
Many thanks to the moderators, can't wait 'til GOTM3.
