NoNewTaleToTell: Was the original Doom 3 the one with Doomguy struggling to hold his flashlight, weapon and PDA at the same time while zombies stumbled out of closets randomly? If so, it has my vote. Very flawed game but enjoyable all the same.
Yes. I think people probably wouldn't have savaged the game the way they did if they had called it something other than Doom. Because it's definitely not a Doom game. It lacks basically everything that made the original games good.
If they had named it something else, I probably would have liked it a lot more because I wouldn't have been expecting a Doom game. It was a fairly good survival game, IIRC.
