it would be nice, but on the other hand, pretty disappointing.
unless they add something else than just new visuals and audio to the game.
That was about my only complaint about Doom3 (that and that the game ran too slow on the minimum and recommended system specs)
I love id games, been playing them since the old doom days, all prefer their oldskool fragging style over the tactical shooter stuff. I would like it if they went for that approach instead of trying to copy zombie games like they did with doom 3. Of course they won't listen to me.
