The ability to save is a given among modern video games, but there doesn't seem to be a save system that can satisfy everyone. As players, gamers want to be able to save and resume our games at any point. For many, even save points are too restrictive; PC gamers are used to quicksaving, which allows the player to save every five seconds in fear of failure.
And that's the downside of saving, really. While it means that players can exit the game without losing progress, it also means that player failure -- as well as player choice -- holds less weight.
