I don't know if it has already been discussed, but i think it would be both fun and useful to be able to play as a human against your AI (or even others AI).
It would be fun because, if your bot beats you, you would feel how good it actually is and you'd be proud to have written it That and the fact that games are just fun to play anyway.
It would also be useful, because you could try some specific moves against your AI to test its behavior in specific situations, that would make debugging easier.
Somes games might be not too well suited for it (games where user input would be inconvenient/slow), but for games such as Wondev Woman if you could click on the cells to chose a move it would be easy and would not slow the games down too much.
What is your opinon this?
