The game I have thought of is turn based, but both players play at the same time without knowing the other persons choice.  That was confusing but think of Rocks, papers, scissor.  Logically a bot does not have an edge over you (at first).  The game works like that but is a little more complex.  With RPS a computer can track your habits and then get an edge but if there are 300+ players it would be hard to take advantage of this advantage.  Sound to good to be true?
