You're welcome, Hollywood Hogan (nice reference to WCW, btw). I'm a Commander Keen fan too (I'm still waiting for a next-gen Keen game), but I think that someone should try to remake Keen as an MvC-style character (I would, but I suck at spritework). Also, one of the songs on the SKF4 soundtrack (Outside Skull Castle, I think) is actually from a game called Nitemare 3D. Still, it's an interesting piece of work considering the fact that one of Nicksoft's other projects, Duke It Out in New York, was a subpar Duke Nukem 3D addon with severe slowdown problems on some maps and one new song that didn't even work.
