I can probably get it done in about 50-55 hours if I sped through and didn't stop to enjoy it and probably as low as 45 hours if I go all bare-bones speedrunning. But I usually take my time, enjoy life, train like a demon, etc. so I've eclipsed 100 hours each playthrough.

Welcome to the Escapist! There's some punch and pie on the table and the rules are thumbtacked to the door. Hope you enjoy it here!

Can somebody tell me why it's great? I downloaded it recently aswell but to my PS3 and I have just got off the train to blow the second thing up and I have yet to be anything but annoyed by it.
Give it a chance. You've only just started. You haven't even met the true antagonist yet.
