This game was pretty easy. The last two extreme challenges were a pain IMO. Takes roughly 15 hours to 100%. Just a heads up, you don't need another player for the multiplayer achievement. I got them by myself.
EDIT: Another thing that was a pain is when you do duels on the blackboard. Your opponent is random so you don't know who you're going to get.
Thanks to Rajeanero for the sig and KillerBEA for the avatar.
