Starcraft, Diablo 1/2 etc are truly great games. But after I switched to Linux, I have stopped buying Windows titles.

I keep my eyes open for games with Linux clients, for instance I've picked up several games with id Software's logo on the box (Doom 3+RoE, Quake 4, RTCW, Q2). To be honest I don't think many of these would have made the cut had I still been a Windows gamer, but I wanted to make a point of supporting them because of their Linux-friendliness.

I would love to buy your products if they were available on Linux.

(Opening up the source of old games would be nice too, and could help keeping them playable even in the distant future.)
