Does it annoy anyone else not being able to save wherever and whenever you like? Why would developers do this on a PC game? When I have to repeat 5 minutes of gameplay that I have already successfully completed, that is called bad game design.
I agree. I prefer to have the ability to save, backed up by an autosave.
If the checkpoint/autosave system is reasonable and saves very often, then I don't mind it. I'd take a checkpoint system over a system that doesn't auto-save at all.
I've had some annoying moments in Skyrim where I've ridden across a large section of the map finding new places, and then die to a group of mages and end up all the way back at the beginning. I turned the "autosave" down to 5min but apparently it only triggers if you open the Menu screen. I've learned to abuse the save button religiously to counter it, but still, annoying.
Oh, and I dislike some games that allow you to save outside of combat, but not in combat. Mass Effect and I think Dragon Age had this limitation. I understand you don't want player to abuse it, but I find that more often then not it just keeps me from saving at the start of the fight because the bad guys have already aggro'd. The only time I've ever "abused/exploited" the ability to save in combat was in Skyrim against a Dragon Priest when I was at low level.
