Games are weird creatures. Always pushing the limits of hardware, and as a result making for quite the game of whack-a-mole for wine.
That may be true, but it is only a matter of time till most game makers begin testing their APPs in Wine, and making them compatible ON RELEASE. Then you will see many gamers rushing to switch to Linux. Aside from that, there are already several software products, besides WINE, than can already play most games right out of the Box. Some great WINE inspired products are: CEDEGA and CROSS OVER. You have to pay for these products, but 99% of the games I have played with them work flawlessly!
