Have you played it yet? I've seen some gameplay videos on youtube which look pretty awesome but I haven't pulled the trigger. Although it is much cheaper than almost anything out there nowadays, and looks to be worth the price of an actual disc game.
Yeah I got it, and have been working my way through it. Like the first one, the tracks get pretty challenging. There are some pretty awesome tracks, I love how you can be outdoors in this one. And there are already a TON of really fun tracks and skill games that others have created already, that can be downloaded- for literally endless content.
I've downloaded a few fun skill games that people have made, including a high jump game, where a bar rises a little higher after every successful jump above the bar. There's also basketball, bowling, stairclimbing (where you see how high you can climb a giant staircase), jetpacking... you name it.
Get it- totally worth the purchase.
