Hmm, well the actual game is only like 40%. The side missions are the other 60%. That was my problem with the game. I'm not a side missions kinda guy. I like to play the main story and I usually don't even bother with the extra stuff and with Arkham City, I was upset that I was forced to find every ringing phone, every Titan can, every Riddle and every hostage to get my money's worth. The main story was just way too short.
