Well, I didn't expect it to have so many bugs. It's annoying to be honest. About the story, a little contrived, definitely a rollercoaster ride. I'm not sure if I'm enjoying it too much though. I definitely miss the dynamic between characters from the first game.
I'm on my first playthough, finished some quests in Arx, currently stuck at "Old Means Gold" because Cat the Appraiser won't buy the quest stuff from me. Apparently it's a bug, and that's what annoys me about this game. You can never be sure if you're missing something, or there's a bug blocking your advance.
I'm a big fan of tthe first game and this one is a bit of a let down so far. I wish it was better polished, because the game could be enjoyable if it wasn't for the bugs getting in the way.
I greatly enjoyed the first and was worried about bugs in this, I guess I'll wait. Some threads at steam talk about save corruption and item disappearing too.
