Don't take my comments as negative though I can see how that could be viewed.
If I was cashed up, I would buy it in a heart beat, dam fast and fun game, that is tougher than you think with that one more game feeling. I had it for around 2 years and clocked over 1500 games, you and your son will love it John as well as others keen on it - congrats.
For anyone thinking of getting it ensure you get a sub upgrade and shaker, this game is so well suited for these features especially the shaker
