Finished the game last night, only had it for a couple of weeks. I don't see much replay value in this game. I'm somewhat disappointed in the game, I'm giving it a 7.5.
I've been playing dishonored for a week now, and I feel like I'm losing interest in it. I don't know if it's the mission based approach as opposed to the free roaming "skyrim" world that is causing this or the seemingly shortness of the game (I'm already on what might be the last or the second to last mission). I'm going to keep playing...I need my $60 worth!
