Think I have covered it really in above comments. Way too expensive for what it was when bought when first released, as you can get it now for a few bucks then yes worth a play.

Addiction level- I really don't find this game addicting, the only bits which had a high addiction level is when you play as Kong, but that has its faults, as its almost just tapping buttons, their is no skill to playing as Kong.
Graphics- I find the graphics a real let down, when you think of the cinematics that where involved in the film, this would have been a great game to show boat the xbox36o's graphics & Capability.
Value for money- This is a real cheap game was originally sold for around £40 now retails at around £20 (£10-£15 for trade ins), but still despite it being cheap i still feel it is a waste of money, as it's a short game, thats nothing new.
Overall I think King Kong would be serious waste of money, that could be put towards a better game, The game has a very short life span to it, and nothing that hasn't been done before, considering this copy is for a next gen console the graphics, aren't anything special (I would say average xbox graphics)
