We have wii.
At the moment we only have a few basic games. I think they came with the system. But if anything.....my 2 year old enjoys "thinking" he is playing!

We are contemplating the "Mario Olympic Games" for the system. I am hoping it will be a fun party game as well as be something my little guy can grow into some day.

We really like the party-like aspect of the system. I am not much of a "gamer" but I do enjoy the wii. When we have friends over, we often have boxing matches, bowling tournaments and even play pool!

Wii Play is a good start for the younger kids. They can also play the sports games that come with the system.

Also, check with your local library to see if they carry any games. Ours has about 20 games and it is nice to test them out before we buy them.

We have had our Wii since last May and absolutely love it. Our 2 1/2 year old likes to think she's playing it, but our 4 year old (and her 5 year old cousin) has had no problems playing. She loves the Sports game that it comes with, Wii Play, and especially Mario Party 8. We have Mario Party 4 for the Game Cube and she's always loved it, also. We bought Wii's Carnival Games for her Christmas present. My husband and I enjoy playing it with her so it is definitely some entertaining family time!
