I wouldn't oppose some save checkpoints built in so it's impossible to make a dead save file though. For instance when you die you can choose the last check point or your last quick save when selecting a file. It would be functionally the same as the last games, without the "poisoned apple" permanent death situation, etc. Naturally you'd lose anything you got since the check point, but it would avoid a dead file.
I would personally just keep the current system.
Plus, how are you planning to make checkpoints in open world like Skyrim?
It's not Crash or similar game so it can work like that.
I prefer current system since it's simple jet effective and good, just like six.
In, out, in, out, in, out, iiiiiiiiiiiiiiin and out... *tadaaah*
And then you hope nothing else gets out after that... except blood maybe... and lot of it...
Anyway!
I hope you get the point (even though I kinda lost it myself). ^_^
No. Keep it as it is.
The only change I want in this topic is more frequent Autosaves.
Aren't auto-saves already frequent enough?
I mean, every sleep, wait you get an auto-save and most of the times you use doors (entering dungeons and stuff) you get an auto-save.
Combined with quick-save button I think that it's more than enough.
