Has it ever happened to you?
After a session with my Redguard, I decided to load my female Nord for a change. When I was done, I saved... over his file.
My most recent character, which I had just completed all questlines with.
A pickaxe to the stomach wouldn't have hurt as much. Skyrim is a very time consuming game, starting a character again isn't something you can do without batting an eye.
Not to mention that I've been playing it for over an year just like most people here. It isn't a fresh experience. Still enjoyable, but a tired one. The idea of starting over is far from appealing, or easy.
