Now we are going to a more childish games because I played this games when I was a child so that's why Is more childish!! And...
I don't know if this is cheating but I will put two games on this because I think that this games are on the same level!!
Like, I personally played more Ice Age 2 but it was because the protagonist is my favorite character, that weird squirrel that I don't know the name, yeah, you can call me a poser.
As I said, I PERSONALLY played more IA2, but with my sister, I played more IA3 because of the multiplayer minigames!!
If you have a sister or a brother, you know that you need a multiplayer game because, if it's a single player game, one of you need to wait for the other to play!
This two are great but if you prefer a good 3D plataformer game, i recommend IA2, because you will have more fun playing it, but if you wanna a good mini-multiplayer game, I recommend IA3!
