It's ok but I wouldn't buy it. Yes there are cars from the Acceleracers monies and highway 35 movies but the game just doesn't give you the same feeling as the older hot wheels games did. The cources are repetitive and the missions are sometimes hard to understand. (And when you do understand them the courses are so jumbled up with different toys and stuff that you can't figure out were to go. The power ups are OK but are kind of hard to aim. And last the color is not the best it could be and the objects are sort of choppy.
Hot Wheels has some decent graphics and nice responsive controls but that is pretty much where the good stuff ends.
The "racetrack as part of a house" (the tracks are all in rooms) has been done before many times and while there are some nice multi-level aspects brought in with ramps and stuff, it is not enough to raise the standard of what has gone before - sometimes a good few years ago.
Despite the stats of the cars to select from being quite different we found little actual difference in performance between many of the cars except perhaps in handling of corners - the supposed differences in acceleration and top speed aren't really there and the slight difference there may be is negated by the power-ups and boosts in the game.
Battle mode is just passable but at least you have the fun of trying blow up your buddies cars. The random weapons allocation can be frustrating and frequently unhelpful.
There really is little new here and unless you are mad crazy keen on racing games or play with some younger kids from time to time I can't really find any reason to rent or buy Hot Wheels - it really just gets old too fast.
