Doom(origional and doom 2)

I know Final Doom has a LAN/Internet thingy that allows you to hook up with a few people and either go Death Match, or try and clear the levels together....never tried it though, it's kind of ancient...afraid it'd blow my comp...

ITs called Doom Legacy, but that feature allows you to use OpenGL without the game being a fag.
