I love this game. It is very fun. It can play 1 - 4 players on Wi-Fi but I have not yet tried it. It has many levels to unlock to bring hours of entertainment. You start out with picking from four main characters, Shrek, Fiona, Donkey, and Gingerbread Man. As you go along, you will unlock more courses and more characters. It reminds of the Mario Kart format, but it isn't quite as good as the Mario Kart DS. This was appealing to me because new it was under $30 and so many PSP games are not that price new unless they are not that good. My 8 year old daughter had a good time playing it too.
