There are quite a few variations of each game, but being that the games are all played the exact same way, there's not much value to the package at all. Not all of the games are throwaways, but there's just not enough to the games to make them appealing to anyone over the age of 5 at best. Add to this the fact that there are only a couple of new games that didn't appear in the original and you've got no reason at all to purchase this game. There are a fair number of unlockables for your characters which is nice, but it would have been nice if they'd focused more on gameplay and less on the number of wacky masks you can put on your character.
Another budget-priced casual title that doesn't strive to be anything but that. Not worth your time or money.
