A. Wii owners who didn't get to play the first game and are bitching about not getting the first game (a completely unrelated fact from Dead Space Extraction). Somehow they think a watered down, less visually appealing, port with some useless side content thrown in would be a better example of EA delivering high end content to the Wii than an exclusive and innovative new entry in the series.
B. People who have some interest in TPS or FPS games, may or may not have played the first game, and have such an obtuse view of game genres to assume there is no way they could enjoy an on-rails shooter or that an on-rails shooter could deliver an experience they've never had before.
C. Wii owners who basically want RE4 with a new story and aesthetic, regardless of the fact that the people who made Dead Space didn't make RE4, that the people who made RE4 saw fit to not bring RE5 to the Wii, etc.. Basically people bitching because their niche desires aren't being serviced by a large multi-billion dollar industry.
