The game runs pretty darn good but not perfect under CrossOver Games 8.1.4 for Mac OS X Snow Leopard. I've had occasional mouse pointer anomalies where the cursor keeps dragging itself to the right (forcing the screen to pan to the right) and I can't stop it. Even if I pull the mouse pointer back left as soon as I stop moving the mouse it drags right back to the right again. The only solution was to exist SAGA and go back in. However, it should be noted that when this mouse problem occurs, I have also been swapping to different desktop workspaces to work on other applications. So perhaps its something with this swapping it didn't like, I'm not sure. The problem is fairly uncommon so it is certainly not that big of a deal but is something that keeps this game from running perfectly.
