Gave it a whirl, did 8 races. Won 3 of 'em (should have been 4 but the game flipped out and moved me from 1st to 2nd with like 2 feet to go even though there was no-one near me...), placed in the top 3 five times of the eight.
The game is kind of fun but I hope they plan on making this an arcade game as it's nowhere near anything I'd pay retail price for...like maybe $15 or so. It almost feels like a game that you should play on an iPhone. It doesn't even feel as complete as Mario Kart. There is zero skill involved for winning, honestly it's all about getting a lead early while everyone behind you beats the snot out of each other. Two of the races I won on was the same locale (some sort of desert area) and both races I won with more than 15 seconds between me and 2nd place...
I'll play it a bit more but thus far it feels like a disorganized mix of Mario Kart and Outrun...but not nearly as fun as either...
