Plays just like DnD or pathfinder. I for one really enjoy this game. It even has these funny parts. I made a Warlock for my party. He makes this inappropriate joke. Then another party member says not now with the jokes. He then replied "I can't help it, it's in my contract".
I could legit make characters all day. The thing I love the most about this game is you can make your whole party. But it doesn't stop there. There are custom dungeons you can play through or even make(I think, haven't figured out how to yet) your own dungeons.
I can't wait to see what else they do with this game. Be sure to get the DLC it's worth the extra money.
