I hate cliffhangers in story-focused games. Sometimes enough is resolved that they're not a
huge problem, but when the things the entire game builds up to are left unresolved and you're stuck waiting around for DLC or a sequel to have any of your questions answered, it's downright disrespectful and enough to undermine all or much of what that game did right.
dtgreene: Incidentally, I could say that the Ancient Cave in Lufia 2 was ruined by the lack of any way to save; the dungeon is too long to complete in a reasonable-length session, so the lack of a way to save in the dungeon ruins the dungeon.
In fairness, the Ancient Cave is 100% optional and presented more as a side distraction for hardcore players. It'd defeat the point if you could reload a save whenever something bad happened or you didn't obtain the ideal items from chests.
