The sci-fi games that didn’t just jump off the weapons rack gave us assault rifles with chainsaws on the end of them. Ratchet & Clank has no connection to the military industrial complex and gave us the same handful of templates within only about 5 years of the franchise. There’s just only so much you can do with a weapon that’s essentially a gun. Maybe you get one really unique-feeling weapon every game, but you can’t get an entire arsenal of that every game.
