My girlfriend bought it for me. She knew I was interested in it. I probably never would have bought it for myself, since I'm pretty sure I'll never actually finish the main quest... let alone all of the side ones.
I never made a dent in Oblivion. I'm almost to level 13 in Skyrim... But I only get a few hours every other week to play. It's going to take pretty much forever.
I guess I really didn't like Oblivion. Skyrim is AWESOME though! I just wish I could do it justice... without blowing off the rest of my life to do it.
