I'm a father of 2 young kids, 7 and 9, boy and girl, and I love to play video games with them. Although competition is fun for me, it only brings out the worst in them. I know that the Wii (U) is generally considered "family friendly" with the Mario mascot and all, but I've had a hard time finding games in the Playstation family that are the same. Particularly in the co-op genre.
I went ahead and played that Disney game with them a few years back (not Infinity) and that was pretty fun, but I found one in particular that they have loved for a couple years now: Rayman.
Yes, the Wii U has the ultimate version of this game, but man, Rayman Legends on the PS keeps my kids coming back for more. The characters and worlds are wild, the levels are challenging and require them to work together, and I hear my kids singing the songs when they are walking around. We started with Origins a few years back and got Legends this year, and both games have really encouraged a lot of imaginative play outside of gaming. The art book that came with the Origins game is nearly worn out from them going through it to copy the art style.
They build "Teensies" out of Lego, they draw countless images of Rayman and Globox, and have written letters to Michel Ancel praising the characters.
My kids don't really mind, but they do tell that no other kid in school knows what they are talking about, though. Is that because the game is not as popular as it should be? I'd really like to see some sales figures for the game. I'd hate to not see another Rayman game come out for the next gen of gaming, if not for me, but for my kids who love the game and have really grown in their cooperative skills as brother and sister.
Let me know in the comments if you have a family friendly Playstation game that is cooperative, or at least one that works well with your family.
