I don't like the idea of FPS'. We'd expect them to behave the humans when they play FPS - they run looking forward and will occasionally look left or right and follow some predetermined pathing that they are familiar with.
With an AI, if we base it on pixels, what they will do is spin around 360 degrees about 60 times a second while moving forward so that it can maximize all of the pixels inputted at a time. It would compare it against the stored level design and shoot at anything that is off (or against character models). I can just see that it's not going to behave like anything we'd expect.
The same would likely be true of an RTS. An AI could scroll the viewport around and click units to issue orders at ludicrous speeds. Even if it had to use the same interface as a human, it'd still have a huge mechanical advantage.
