Shit, how could I forget Mirror's Edge, the best example of what I meant and one of the most interesting games in the last couple of years.
Anyway, yeah, I know that Dead Space is Resident Evil 4 in space. From your post it simply seemed to me that you were saying that every game they made was a direct clone of another game. The only thing Dead Space took from Resi 4 was the gameplay itself, and even then it added it's own little twists like the dismemberment and the zero-gravity and no oxygen sections.
Plus, please tell me where the big original games from other publishers are. Only ones I can think of off the top of my head are Bioshock, which was even more derivative from SS2 than Dead Space, Assassin's Creed, which was basically Prince of Persia meets GTA, Deus Ex: Human Revolution, which stands out in today's market but took most of it's ideas from 10 years old PC games and was, you know, a sequel, and possibly Metro 2033, if only for the Eastern European take on both the post-apocalyptic genre and the linear corridor shooter.
Let's put it this way: I can't really imagine anything as derivative as Activision's Singularity or THQ's Homefront being released by EA in the last couple of years. Oh wait, truth be told, there was Dante's Inferno. Still, though, I think you're greatly exaggerating about EA and are kinda ignoring that every other big publisher is more or less the same (Ubisoft, THQ and Eidos/Sqeenix being a bit better than Activision and EA when it comes to innovashun).
Who would have thought that the day would come when I would defend EA in an argument.
