What're you going on about? I just played through the original half-life (c. 1999) on vista 64-bit, and it runs fine. Sure, they're not designed for a 64-bit OS, but they still run fine; Vista has a separate program folder for x86 programs. (which most programs, as well as games are. Firefox is running in 32-bit right now; I'm using it just fine) Edit: Blade and Nadril got it before me, I think I was impatiend and clicked the reply button before the entire topic had finished loading :|
