Whats your best early game strategy?
There's really only one approach for consistent success and that is
aggression.
Be aggressive from as early as you can be sure your aggression will result in net gains and then build on that.
Obviously, by aggression, I mean ostensibly
war, but also go after the best city locations aggressively, and aggressively get as many goody huts as you can. If you try to play nice, the AIs will use their bonuses to beat you.
I usually start like this on large pangaea or large/huge continents:
- Settle in place, unless there's an excellent spot worth delaying your start for.
- Micro the city's tiles to get maximum production whilst still growing.
- Scout, scout, monument, warrior, warrior, worker, warrior
- Use your initial warrior to scout the surrounding area for goody huts, 2nd and 3rd city locations and 1st and 2nd victim AI.
- Bring home your initial warrior to help defend against barbs once he's done his job.
- Use scouts to scout the rest of your landmass out, finding the other civs, city states and goody huts.
- Once they've finished scouting, bring your scouts back home to help protect workers.
- Go liberty and get the free settler and free worker, then start working down honour.
- Research whatever you need to improve lux tiles, then head straight to iron working.
- Sell your developed lux/s to the highest bidder/s.
- Sell OB to everybody.
- Keep all your cash to upgrade your warriors to swords.
- Pump out some more warriors.
- Hold off placing your third city until you know where the local 6 iron deposit is.
- Research iron working.
- Settle on the six iron.
- Upgrade your warriors to swords.
- Take the best cities from your nearest neighbour/s.
- Continue...
Sometimes there's not a local 6 iron, but usually you will find at least a 2 iron deposit and then you just have to use a couple of swords to do most of the heavy lifting and use warriors to back them up. You'll probably take more losses, but you'll just have to build/buy more replacements.
If you have no iron at all, you'll have a harder time of it, but you can still take a few cities before your losses slow you down. In these circumstances it might be better to hold off taking on your 2nd victim until you can get iron from somewhere.
If you don't have any iron at all, but your neighbour does and has actually mined it and built swords, your best shot at early aggression towards him is probably to send every fighting unit you've got at his iron deposit, pillage it and then try to use the terrain and flanking to take out as many of his swords as you can. If he's settled
on the iron, you need to take somebody else on first and get your own iron ASAP.
This approach to early game dominance works for me because the tactical AI is a bit thick and is only really any good when it has a large tech lead, or late game if it has tech parity and can use lots of siege/bombers etc. Otherwise it will happily suicide it's units until it has none left and then beg for mercy, which it wont get until you have all it's good cities and then only in exchange for giving you everything its got.
