I tried Crossover with some very simple old Windows games (Shanghai, Scrabble, etc) and it flopped miserably. It wouldn't install most of them, and those that did install did not run. The only success that I had was with Windows Solitaire, which ran simply by clicking on it. I had such high hopes for it, since I wasn't trying to run anything demanding in the least. Fortunately I finally found enough Mac-native games to keep my wife happy that I no longer need Windows of any kind.
