Naaaah, he oughta check out Episode 1. Now that has great level design and an awesome atmosphere. Then again, that whole atmosphere part maybe the nostalgia factor for me .

As for source ports with jumping and mouselook, there's a whole shitload of them. There's ZDoom, Doom Legacy, EDGE, Skulltag (which is also a multiplayer port). As for Open GL stuff and the likes, there's always Risen3D and JDoom.

Jam it back in, in the dark.
