But not so functioning as to formulate grammatically correct sentences? I do not believe that Civ games have required thinking to beat. At most, they've required knowledge of game mechanics, which is not necessarily the same thing. Extended observation of the Civ 4 Strategy Forum over the course of a few years shows that a lot of the players posting there are not so much concerned with thinking as with how fast they can bulb Liberalism and assume they've won after that point. Which is a matter of rote. It's very possible to run these games on what is essentially autopilot at any level of difficulty.
