Treu, I think M.A.G has a lot of potential when it comes to sales since it is a FPS and cosindering how games such as KZ2, Halo, COD, resistence sell, MAG should be able to sell fairly well as well with the right backing.
Heavy Rain should be advertised in Cinemas or even have someone like Jonathan Ross review as if it were a film.
I think I should get hired by Sony to do some marketing work for them :p
