All it needs now is a "Launch World of Warcraft from my Windows partition" menu entry, and it'll take the world by storm.
You do realize that you can do this with Wine, right? It's how I play. I never ran the installer in Linux, I just told Wine to launch Wow.exe on the NTFS partition and it worked.
Wait... since when does WoW focus on "casual" gamers? I'm sorry, but a game that I have to play often just too feel that I have made my 15$/month worthwhile isn't what I call "casual".
The fact that YOU feel like you have to spend that time to make the $15/month worthwhile doesn't affect the fact that many people consider 10 hours per month to be plenty. Some people log in, work on some quests or whatever, spending maybe 2 hours at a time twice a week.
What? You labour in an open-topped fabric-covered doorless half-height cube? Good god, that's barbaric!
No, I share one with 3 other people.
