I heard it's more like 10.... just with no towns to explore... you go through towns but you don't really interact- which blows. There are side quests, but I think it's mostly killing monsters.
All I know is what I saw from a few videos and I just can't get excited about it. I loved exploring and getting super strong and shit. It looks alright, but not as fun as it should be. I guess I'll see. Supposedly it gets better after 25 hours...
