So I've got a Let's play series on Skyrim, so I won't be just doing one I'll be doing more. (Classes)

And I wanted something different, like an alternate beginning to the game to make things interesting.

I've seen a few alternate beginnings, but I'm worried it's going to destroy the experience and start glitching out.

Any suggestions, thanks!

I've used Live Another Life (which I'm guessing you've heard of already or I'd link to it) and I can honestly say that it has not caused me any troubles at all. I haven't ecperienced any glitches in any game I've used it in, that I am aware of. I love the mod dearly.
