Ages 3-6yo. IMO, the Dora/Diego games are the best intro games for young beginners (3-4yo). Little children will be interested and capable of playing without much parental assistance. My boys like Dora just as much as Diego, but some 'macho' boys may prefer Diego over Dora.

Ages 3+. This is exactly what you'd expect from the title. It isn't deep, but it is easy and entertaining enough for early gamers to enjoy without the frustration that comes from games requiring more dexterity.

Ages 3+. Wii Sports remains one of the easiest games for little ones to pick up and they love accessories. This makes a good collection of family-friendly games all the more entertaining. And it's Nerf, so you have less concern about them losing control of the controller and hitting themselves, their siblings, or your expensive electronics.

Ages 4+. Outstanding fun for the whole family! One of my top recommendations! Similar to Jenga, except you don't stack blocks, you knock them down or otherwise manipulate them. You will enjoy this just as much or more than the kids.

Ages 4+. Later tracks will become way too challenging for young kids, but the intuitive steering-wheel control makes this Kart racer so much easier than all predecessors with traditional console controllers.

Ages 4+. This game involves fighting, so if you don't want the kids exposed to it then skip this one. But the game design is brilliant and you'll enjoy as much or more than they do. You can play cooperatively, too. The youngest can join you as a "force buddy" and just work the nunchuk when you're a jedi.

Ages 4+. Maneuvering through the world map & story mode may be too hard for younger ones, so you will have to play a bit on your own to open up a bunch of the mini-games, but then they'll have plenty of easy, quick options. No need for a long attention span or complex thinking - every mini-game makes it clear what you need to do with the Wiimote.

Ages 4+. My 4-year-old had trouble with the Gamecube version of this title, but did much better with the Wii control scheme. Mario Kart is a more enjoyable racer with more appeal to older gamers, but this one is worthwhile especially if you're fans of the film.

Ages 4-6. I try not to gender steer my boys too much, but the princess-pretending and dress-up features were beyond my comfort level. You make the decision for yourself. Younger children will need more assistance.

Ages 5+. No way to lose. You always respawn at your previous location. Enjoyable for multiple gaming skill levels. You will enjoy helping your younger children with the challenging parts.

Ages 5+. Not quite as entertaining as the Lego games that have come before, but still accessible to children and fun for adults.

Ages 6+. A fun single & multiplayer game. Younger children may be able to dabble with this, but to avoid frustration requires stronger gaming skills.

Ages 3-6yo. I know this is a GC game, but it's compatible with the Wii and I include it because it is the single best traditionally-controlled console game available for young ones (3-5yo). It only has two controls to worry about (movement & action), it's simple yet entertaining for little ones, and plays just like a Dora episode.
