They said that DOOM will come out soon but Wolfenstein look good so I am trying to decide what to do.
Well I'd assume Doom will also be 5 bucks so if you don't mind spending 10 dollars on two id games get both!
I would wait for Wolfenstein and Doom RPG. Let's face it - you played those two games 10x times already, do you really need to play them again? RPG is at least some variation.
I'm waiting for doom, wolfenstein never made it into my childhood. I remember doom on my Apple Power PC
Personally, I plan on waiting for Doom RPG. Never been a real big fan of either Wolf3D or Doom, but I think the RPG elements of Doom RPG will keep my interest more.
