It looks like the ever-popular Vista may be the impetus which drives game developers towards open platforms. Jonathan Blow, the author of the long-delayed, very original, and kind of quirky indie game "Braid" has decided that,thanks to Vista being so annoying, he is going to develop and release Braid on Ubuntu.

such as Id Software have bothered to release or develop games on the
Linux platform, but now that the more popular indie developers are starting
to look at it, the commercial mainstream might not be far behind.
