I tried this and quit in like 2 weeks. There is a ton of quests and the game is decently designed, but it could only hold my interest for so long.
The game is really slow paced, and harder difficulties = less exp? Bad idea if you ask me. I wanted to do like "Hardcore" mode ("Ultimate", I think it's called?) but that requires playing through other characters first and the exp gain is purposely decreased.

The graphics aren't pretty enough and the gameplay isn't fun enough for me to invest so much grind time.
