I love skyrim, and I spend many hours there, but I get things wrong with the build, I change my mind about how I want to play. I didn't even draw a bow until after 40 hours of play, and realised how great it is. Now I regret spending perks in heavy armour that could have been used in archery.
If I restarted I would lose a bit of interest, I've put 55 hours into this. I would like to have the chance, just once, to correct those mistakes. Theres nothing wrong with spending time in a fantasy realm, but when it blurs your world so much that you have to condemn others who want something you don't agree with, it's time to check yourself.
I recently rolled a new character. He's level 12 now but 90% of the quests I did on him is different than what I did on my first toon. The playstyle is completely different as well since my first toon was a mage while my new toon is a sneaky thief-assassin. Don't be afraid to reroll but if you do, make different choices and your experience will be different as well.
