Hi, I had just gotten a game called "Dust: An Elysian Tail" and to be honest it's pretty good, it's a action/rpg that plays really smoothly, and has quite beautiful backgrounds, and a cute art design. Also it has talking anthropomorphic animals so the kids would very likely enjoy it. (Rated E10+)
(I tried sending this personally through "Send a message" but it doesn't work for me, sorry ^^;)
