My son has the Wii Hot Wheels: Beat That video game.
I have watched him play a lot of times and I will say it is a fun game. It really is not for the serious gamers. I feel this is a perfect game for the 10 and younger crowd. It is very easy to learn. My son has unlocked many Hot Wheels cars and I have not seen him get frustrated with it.
It is rated E and I like the game because there is no violence in it.
Currently this is my son's favorite Wii game. He really enjoys it. I have played it a few times and found it is a fun racing type game with multiple loops, ramps, jumps and drop offs.
You can go on a variety of different courses so it does keep it a little interesting.
I feel this game is good for those younger kids that like racing and especially Hot Wheels. I personally do not feel it is worth the $49, but that is pretty much the going rate for any Wii games.
I have no problem recommending this game to friends that have kids and looking for a non violent but fun video game.
