You can now get this game for free. It looks like a cross between Trials and the show Wipeout. It could be fun, but the barrier for entry is low risk. At 58 MB it won't even take up a ton of HD space. Give it a shot.
 
linky
  

edit: If free isn't enough, remember that this has 200 achievement points. :)

Go watch the Quick Look for Wipeout. This is pretty much that, except it seems to have more responsive control, but a lack of hilarious ragdoll.

Damn, now I want a bag of Doritos.

I'll have to download this. I remember playing that T-Rex Doritos game and getting 190 Achievement points in about 15 minutes. 

Theres also the links for another free xbla game and another 200 points Here :-  http://www.giantbomb.com/forums/general-discussion/30/2-free-xbla-games/470425/ 
 
:3

This is the better of the two games and is definitely worth a look. (It is free after all!)

I liked Dash of Destruction far better than these poop piles

I actually remember being pleasantly surprised by Dash of Destruction, but then again I went into it with zero expectations.
 
Having said that, I never played it again after the 20 mins it took to unlock all the achievements.
 
Still, free's free. So I'm getting this :)

This is singularly the most horribly frustrating game I have ever played. Within 10 minutes I wanted to break my controller and was "Cursing like a sailor" as my husband put it. 
 
I will kiss the feet of anyone who can get all the achievements in this game. After I call the mental institute of their choosing to have them committed. 

You know what would make this game about 30% better? The ability to restart the level without backing out to the main menu. I don't know about the other 70% though.

If it's as easy of a 200 points as Dash of Destruction, then I'm down.

wait...wasn't it always for free?

This game is so infuriating, but it was better than I expected it to be. Now that I know the back button restarts the level, I will jump back in tonight. But seriously fuck this game.

This is fucking hard

Gold on all levels, and 4th level in Japan under 1min 40sec is NOT a piece of cake.
