Spongebob Squarepants: for PlayStation 2

My 8 year old nephew is video game fanatic. This was one of his christmas presents, and we've been hard pressed to get him to play another game for a while now. I can't blame him though. I've joined him for this game, and find that it hooked me too.

Lights, Camera, Action is multiple games to play with this. There are some that team you up, but most of the others are competitions. You can either play up to 4 players, or just play against the computer. It also offers degrees of difficulty, and you can choose to play up to 5 games in a tournament. It gives you the option of picking the games yourself, or letting the computer choose random ones.
I know you have to unlock games, but I'm not exactly sure how you do that.
I find the variety of games fun, and it's able to keep the attention of my nephews. It's not so hard that they get frustrated, though my 4 year old nephew has a little trouble with it. This is a great game for kids.
