There are several other games I've run successfully via wine (at least one on Unreal I think too), but I purchased all of them before I switched to linux. I don't puchase new games without native linux support, because even if it works initially under wine, it might break with a patch release and then I'm stuck on an older version, just _hoping_ that they fix whatever broke wine compatibility, which they might not because I'm running it on an OS they don't support. It's just not worth paying money for a commercial product that the developer has no obligation to maintain.
