The obvious choice of keeping winners and throwing out losers proves absolutely NOTHING after one game, and there have been many discussions on here that place the number of games needed to detect a clear difference between programs at 5-30. When dealing with the very small differences between two sets of weights in the same program, I don't think there's any upper limit to the games you might need to draw a correct conclusion, and so instead of "evolving", you just end up with a bunch of more or less random weights.
