The hype is there because it was one of the first "3D" shooters, and one of the first games where obscenities were allowed (they are nothing compared to today's games). It's a sequal to a classic 3D game. Just the name is where the hype comes from (Kind of like a new Zelda, Mario, Sonic - although sonic has been mostly crap recently - game.)
I'll probably check it out or rent it. Not big on collectors edition stuff though, Just more crap to sell at a garage sale for ten cents in 10 years.
