It's definitely much more polished than the first installment. I've played for around 40 hours and can probably count the bugs I've encountered so far on one hand.
Is it the same combat system as the first? No matter how hard I tried, it just wouldn't click for me. Ended up modding myself invincible in order to beat the game...
I'll do it again too if I need to because I love everything else about the game, but I'd prefer not to
It gets too easy too fast IMO. I haven't done much of the main quest yet but I'm already a invincible human tank and killing armored enemies with single hits. I might swap my sword with a lower tier weapon to get a bit of the challenge back.
