The two most recent Fallout games have been critically lauded, and has little loot variety as a whole. They're also RPGs. Conventions aren't mandatory. Skyward Sword threw out half of what made the series what it is today and is getting rave reviews because of it. BF3 has a shitty campaign (by most standards), something pretty important in FPSs, and is getting good reviews too. I hope you see my point here.
