When the blisters come up and your thumbs start to hurt, you know it's time to put it down but not because you want to, because you have to. There are very few games that I will sit down and play for ages but this game is very very addictive. The graphics are really clear and the game is really easy to get into so no having to sit down for an hour to read the instructions before you can play. I don't know anyone who has played this game and not loved it. There are not many games that I think you get your money's worth out of but this game has taken up more of my life recently than I'd like to admit. If you're thinking of buying this game, all I can say is do. I can't wait for Tony Hawk 2 to come out tomorrow.
