mrcrispy83: I mainly just want to play doom 1 and 2. :(
bevinator: You're much better off using a source port for the early games. Just download ZDoom or one of the other ports (they're all free). At that point, the only thing you'll need are the original doom.wad and doom2.wad files, which can be acquired from a variety of sources. *cough* Most of the ports can also run Heretic, Hexen, and even Strife, so you can get compatibility and improved play out of those games too.
I know, but I still would like to have a legal copy in some form some day for moral reasons.
and well it's hard to explain. but like when you pirate something, there's no barrier for entry, it's not any harder to pirate one game than it is to pirate a thousand games. But then you'd just have a thousand games squatting unplayed on your hard drive. there's no motivation to actually sit down and play them, no pressing desire to play them to get your money's worth out of them
like I pirated Duke 3d and Blood a while back, but I never actually got around to playing them until I got legal copies from GOG.
