I've gone fully to Linux and all my games surprisingly run. I was ready to ditch some but I even got Blizzard stuff working which was my main concern.

I switched to Mac around Vista and never looked back. For games, enlightenment is realizing the PC gaming tribalism is dumb and PlayStations are actually really nice. It's an appliance that plays games without giving you trouble, in a comfortable place instead of encouraging you to spend even more time at a desk.
