I've played this one before, quests are very easy! For maximum achievement (80) in the game you will need a lot more time. Too bad there is no more serious hard quests!
Probably the only game with quests I didn't have to start from scratch for , I already beat the game so the only one that didn't unlock after loading it up was Steel Set. The game is great, pretty much all of the quests are obtained through normal game progression, beating it takes some grinding though iirc.
All the Quests are easy, I enjoyed playing it while it wasn't addicting. I got very far and near the end. Having 75/80 Badges. So close. Guess what? Yeah, it deleted my profile/save. Thanks God I got all the Quests before it deleted me. I would be so pissed of
