Alan Wake is in a totally different league than Heavy Rain.
Alan Wake will be a "real" game, a true AAA title getting 93% on Gamerankings and selling 3 million copies minimum. Top notch graphics, gameplay, story, atmosphere.
Heavy Rain, although it's one of the most interesting PS3 titles, is said to be a "Quick Time game", sort of like the 90's adventure games where you haid a nice panorama screen with very limited freedom to move around and do a lot of stuff. The areas are small, that's why they have enuff memory available to great textures, but for example view distance is unheard of etc.
Heavy Rain is a cool experiment, but reviewers will most likely severely punish it for weak gameplay and give it low 80's on Gamerankings. Sales 1.2 million tops.
