This just in: Even in simplistic AAA games with bots, the AIs are better than human players, we have to dumb them down to keep the game fun.
Thats because 99% of AAA games are twitch games. No strategy involved, just reflexes. Games like COD, Halo, et al. really limit what the player can do and it really is the fastest mouse wins. So they have to limit the reaction time of the AI to what a human is capable of.
Now if you look at strategy games like Civ IV, you had to give the AI unfair advantages to put it on equal footing with human players. But turn based strategy games have a lot of fuzzy logic. So really an AI mastering COD is not news, we can have been able to build bots with superhuman reaction time since the 90's. Wake me when they can master a city building sim as well as a good human player.
