My best cheating AI moment was when I was allied against the babylonians with the Americans and the americans were way behind in tech level. So I decided to share so they'd have a better chance. Well as soon as I gave them the new tech, all their units in the field upgraded. And so did the Babylonians.
Anyway, I thought Civ3 was fun, but at later years when you have a large empire its really hard to play.
Um, the units were upgraded in the field? Such blatant cheating really substracts from the game experience, if you ask me. But, alas it seems the only way to make the game challenging once you figure out how to win.
And about late eras, well, I don't really have a hard time playing. I have a hard time wiping the other civs from the map, but that's what space race and diplomatic victories are for.
I think however that early expansion has been placed too much emphasis on. It's really hard to keep an advantage over the AIs without building a thousand cities in the BCs. You can get the cultural and space race victories easily with few cities but in a small territory you will usually be hard pressed for resources. I often end up invading some fool to take their resources... but that's a whole mess. War is no longer an easy way to win unless conducted very early.
And why the hell does every worm in the map declare war on me when I nuke someone back to stone age? I mean, I would understand it if they established trade embargoes and signed MPPs, but declaring war on the guy with a thousand nukes? What gives?
