This game actually isn't given enough credit. Me and my four year old son enjoying playing co-op. It's varied and fun.
The game also has some depth and variety. There are fighting sections that incorporate brawler game mechanics, puzzle solving sections and some RPG elements that allow you to upgrade your characters as the story progresses.
I'm a hard-core gamer but I can appreciate a decent family game I can play with my 4 year old son, 8 year old daughter and my wife without hating it.
This game is entertaining and the production value is pretty good. I didn't experience any bugs, the cut scenes tied the story together and a variety of game mechanics kept things interesting for me and my kids.
I give this game a thumbs up, try it with your kids if you are looking for a family game. There are fighting sequences so it's a little violent but no blood.
In a sea of bad licensed family games, this one stands out!
