My very first, I scrapped because I didnt like how he ended up looking - so I recreated him, sort of, and with lessons learned I knew how I wanted to distribute my perks. I musta dumped at least 10 hours of gameplay, and retracing my steps was kinda hard.
So far tho, the most recent character which has over 40 hours in him, is great. He looks the way I wanted, and now that im lvl 35, Im having a hard time lvling, and have started dabbling into skills I previously ignored, like sneaking, and archery.
Tried creating a female breton mage\sneak archer, but restarting everything was a bit tough. Great thing about that character is, I'll be using her to get into the Mages\Thieves guild and Dark Brotherhood, which im completely disregarding with this current playthrough.
