This is a pretty easy game but it becomes a deep game with newer levels. Moves are handled like any other extremely sports game. There are some neat features such as a balance bar. The game has a good cast of characters, each with their own strengths and weaknesses. The game is very fun to play and the control set up is great. The replay is good as well since each level can be replayed and there is more freedom then in other games.
While it may not be breathtaking to look it, it does look nice. The characters are realistic in design (though not in physics). The levels are huge and there are many active objects in each one. There appears to be no slowdown but there are some polygon break-ups. The polygon count is not very high and the graphics are somewhat bland. But overall, the graphics are good.
The sound is really good. Noises and sound effects are accurate. The music really depends on taste. It works for this game though.
Final words: A fun extreme sports game that anyone can pick up and play.
