Well I don't plan on running anything after 2000 (maybe besides Theif Metal Age). But it would be cool to get Unreal, Quake, Decent and of course the older Jedi Knight games and some of the other great shooters. Other than that I was just gonna try and expand my playing base to classics I never got to try.
I was like five years old when I played our original 98 PC, so I feel like I'm making up for lost time. Sure I could run some of those on revised steam versions, but I certainly couldn't do that on original copies.
