Has the raging popularity of the modern console FPS corrupted other genres? The "realism", trite campaign mode writing and ultra competitiveness of it all, bleeding into the rest of the scene? Sure, popularity alone means there are fewer Katamaris than CoDs in development but the popular game designs generally tire themselves out eventually. FPS games seem to influence each other more than anything, anyway.
The bonfire of love that burns for console RPGs, on the other hand, has seen RPG elements inserted into just about everything, perhaps in a contrived effort to make the average game more hooky and rewarding. I'd say the proliferation of an RPG flavour across console gaming marks the era in a more meaningful way than the hugeness of the FPS.
