This comes up in one form or the other very often, though, doesn't it? Company x releases software y with a Wine wrapper advertising "native linux support" and users get upset. Personally, I'm glad they're thinking about Linux and I think Wine fills a great role as a "transitional" step between Windows and Linux, but I don't think it's any good to encourage using Wine over making the game more portable. Besides, doesn't HIB have some rule about requiring all games to support Linux natively?
