I can't upgrade windows, because the computer I'm trying to accomplish this on is owned by someone else, and as far as I know, I don't think they'll want an upgrade in OS on their computer, since it's partly used for configuring the projector. I usually have unrestricted access to the computer while nothing else is going on (and access to the projector while working), so getting good games for the PC is usually a must (unless I'm willing to supply my own through programming. Lots of it).
