Unreal
I can't believe that this game has never been ported to a console. I had this game back when it first hit the PC, and to me it was an incredible game. It truly was "unreal" for the time period that it came out in. I mean, this game was the game that basically took PC gaming to a whole new level, far beyond the available consoles at the time. But it's suprising that this game never got released on the Dreamcast or even the PS2 or XBOX.
Man, I hope there is some point where this game gets ported to a system. Maybe as a bonus in a new Unreal Tournament super 2006 game.
