Well, my assumption is that if they are going to bother getting a program to run .exe files, they are probably not just running the game so they'd want something good in general. Wine is problematic (at least for me, maybe for a computer wiz...not so much) and I run several programs through it so it's about time I got something better that won't have so many issues. Wine seems to only work best with older programs because they've resolved a lot of issues years ago. For example, I have no problem running programs like GIMP or PixelShop through it.
Side Note: Maybe this should be moved to tech questions section of the forum? Just in case there is another confused Wine user.
