As far as the developers history, I'm more inclined to say at least id will release this game, where as Half-Life 2 might not see the light of day this year.
Hate to burst the idiot bubble that you live in, but Doom 3 was also originally scheduled for last year and was also delayed, without reason, for another year."Let he who is without sin cast the first stone."
Who's the idiot, Dagok??id have never announced a release date for DOOM 3, so how can you say it was supposed to be released last year? John Carmack has said "the game is very close now" and we have no reason to doubt him.
Valve, however, did announce their release date for Half-Life 2 (Sept 30 2003) and denied a delay right up until a week before that "deadline". Can we believe anything Valve say?
Gabe Newell just wanted ATI to sell as many video cards before the announcement of the delay as they could because of the $8Mil ATI gave them.
Regardless of all this BS, I will purchase and enjoy both of these games. I trust that DOOM 3 will be out soon, but hold no trust that Half-Life 2 will too. I hope to be pleasantly surprised.
Enjoy both!!
