Buzz! Junior is so far the only game aimed at kids that I've ever reviewed.
Recommending Buzz! Junior: Dino Den is difficult. Ultimately it all depends on the age and tastes of your children. The Wii remains king of the party games and if you're used to having games of Mario Party 8 or Wii Sports with your family then Dino Den might feel a little flat. However, if this isn't an option to you and you're looking for something fun and accessible that you can enjoy playing with your young ones, then Dino Den is good, clean fun and if you've already purchased the buzzers for another Buzz! game then it's good value to boot. However, if you already own one or more of the previous Buzz! Junior titles then (unless your kids are absolutely nuts for dinosaurs) there's not really enough new content to justify a purchase; there's only so much you can do with four colours and a big red buzzer.
