There´s already a petition for this: http://www.change.org/en-GB/petitions/rockstar-games-release-games-for-linux
It would be nice if they released it. I would also love to see Vice City and San Andreas being ported to Linux, I get a bit nostalgic when I think about how I used to play those games back in the days, it would be nice to re-play them.
