I always hated save points. RPG Maker 2003 lets you save anywhere by default. Still, lots of games made in RM2K3 have save points, which means they forbid you to save anywhere and force you to look for specific places to save. So, when you want to stop playing, you can't just quit and come back later... you have to look for a save point, which sometimes is not as near as you'd like.
It is worse when save points are badly placed. There are games with huge cutscenes before difficult battles that force you to rewatch the entire cutscene in case you die in that battle.
So, unless there are places in which the player may get stuck and you don't want him to be able to save there, I see no reason for not letting the players save anywhere.
Polymorphous Perversity is, in a way, a game about morals and choices. Will you pay the farmer to have sex with his daughter? Will you fist the tranny looking for treasure inside her? Well, some choices are important, some aren't. But in a game where you can save anywhere, it's very very easy to undo those choices. Just save-do-regret-load. I don't want this to happen. So, for the first time, I'm thinking about adding save points. But I still hate them, saving anywhere makes the game a lot friendlier.
What to do, what to do?
