Sorry, but Soren's opinion on this completely sucks. In a balanced game, an AI that plays well *is* fun. You don't create an idiotic AI then heap bonuses on it and pidgeon hole the player and call that "fun". That's called "lazy". Nice try though, Soren.
I disagree. If I want to play with players that just try to win, I'll play with humans; but normally I'd rather do that on the tabletop, playing a game like Diplomacy or Illuminati, where you get the maximum interaction *.
The diplomatic game in Civ is interesting - but it works because the AI doesn't just try to win, because it can actually like you and not DoW on you the moment it thinks it can win. If the AI just tries to win, the space race and cultural victories become irrelevant - just as in multiplayer, there's no getting close to them without being stomped.
I'm not saying there isn't a middle ground - and indeed I think the Civ IV AI is too far over in one direction, something which is particularly well illustrated by the standard "stop research" culture victory. The game would be better with a fine line to walk there between defence and culture. But I don't think an AI that simply seeks victory is the best option, either.
* interaction, noun: attempting to tell plausible lies until your tongue turns black.
More like AI's randomly dowing each other .. at least that's my limited experience.
