I'm not the one saying this will be a revolutionary game....as q3 wasn't in the beginning IMO...the mods made it was it "is"/"was" today!
But I can say for sure that Doom3 plays great (scary as hell), has nice gfx, and the sound fits the atmosphere.
I ain't back up those points with some e=mc2 high detailed tech talk ..cuz a) I dunno shit about game programing b) I give a shit...
You can't argue about taste and that might be the problem here....If you not like it, don't buy it...I got lot of good gaming with it ...that's whats important for me.
