A computer vision system is still disadvantaged in that it can only see what the player can see, and no more than that. For example a wallhack won't work well as the cheat simply can't get the locations of all the enemies, and can only highlight them when they actually appear on screen. Also most of the games you listed above are relatively simple to work with both in terms of rules and graphics - it would be much harder to have a functional bot for the many variables involved in a 3D FPS game with fog, bullet drop, friendly fire, and so on.
