Is this really a question...?
RE had:
1. Name recognition
2. Advertising (and hype)
3. A sequel to one of the most successful games on the Wii (see hype)
Dead Space on the other hand pretty much had the same limited support and strikes against it as all other Wii games. True, it had limited hype, but only those people seemed to go out and buy the game. Also, internet advertising and 'core' fans don't help sell a game, as games like Madworld, Muramasa and even Zack and Wiki can show. You need full support from the company to really help sell the game, which includes full market saturation of ads (including all forms of media such as TV) and making sure the game is stocked in all available stores.
