I want an actual Space Marine FPS…well, we had one recently…but it involved the damn Ultra Smurfs, damn codex humping blue bastards, still marginally better than the Blood Ravens…marginally. Anyway, but I digress.
I wouldn't say generic, after all even those in the same genre are unique. Not all the 3rd person fantasy RPG's are made equally. WoW has it's strict class and hit-key system, Rift has deep class mixing and customization, Neverwinter ditched the Tank/Healer/Dps thing for classes more based around controlling the battle, Guild Wars and Aeon went for more real time combat that factored in terrain and height. And each of them has their own world, with their own stuff in it.
