Oh man I remember playing that. Back then the PC I had could barely run it but I so enjoyed charging forward with some grunts in wedge formation in front of me and hitting stuff in the head with large boulders.A lot of the ones I'd like to see have been mentioned repeatedly already.
However, one that hasn't is a sequel to what I think is one of the most underrated and underappreciated pc games ever:
I guess I don't see how Commander Keen is any more childish than any of the side scrollers from back in the day. Now, simplistic mechanics, of course, but that's what made the game fun.Anyway... Commander Keen was really cool, now, even though I probably still like it, it seems so childish >.>
But..... as for a sequel... I can't see how else he can fight off aliens, I mean one of the latest games was in his dreams...
