It depends on the game, but I really don't think you're adressing the real problem here. It isn't unlimited saves, it's the lack of penalty for deaths!
OT: All games need quicksaves (saves, then quits you automatically, and then deletes when reloaded) for you know, life... I think RPGs that let you save anywhere are too easy, I like it when you have to go to a specific place to save. Action games need checkpoints, maybe placement of them could be better, but they should always have checkpoints. I once played a game that forced you to save before a particularly hard area and then punished you if you reloaded. It was an RPG, and it you died it reset you with less stuff. It was to prevent grinding the same place without skill just trying to get lucky instead of leaving, getting better, and come back more prepared. It was really annoying, but interesting nonetheless.
