The problem with video game bots in games like Civ is that "playing well" is not actually the core goal of the devs. Rather, it has to be enjoyable to play against and easy enough to build and debug in the limited time available until release. Given those constraints, most game devs just give the bot free resources and call it a day. If somebody would bother to put in the time to make it, a well-crafted Civ bot could probably roflstomp every human out there just by virtue of perfectly micromanaging its production in every city on every turn without effort.
