[quote name='Mr. Anderson']EL DOOM 3. UC 2 is like eating a ham sammich without mayo. It's just not complete.[/quote]
You're judging a demo. I think there might be a ton of stuff you didn't pick up in the demo, different attacks, etc.. As on AIM, you mentioned you were expecting "UT2K4-like gameplay".. this is not Unreal Tournament, this is Unreal Championship.
I'd get both, but if you get Doom 3, get the CE.. I mean, it includes Doom and Doom 2, with possible Live support and definate multiplayer on the same console..
