Is that it?
This game is enjoyable to the extent of the first very short play thru. The chapters in themselves are really short and the unlockables give you no real reason to replay the game once you have beaten it.
If you want the black spiderman costume then by all means complete every aspect of this game, but once you have obtained it what's left to do other than look at peter in the suit with no other missions left to complete.
I am a fan of spiderman so I enjoyed his agility, web swinging and wall crawling abilities. Some of the boss fights were fun too.
