Ditto on Mario Kart DD. Non-stop FUN. I have about 30 games between my daughters Gamecube and my Xbox and I probably play Mario Kart at least 70% of my game time. Just my 2 cents.
Any Mario game should be good. My 3 year old daughter loves Mario Kart DD, Mario Party 5, and Mario Advance(GBA). She can already beat me on some of the mini-games in Mario Party, and i've been gaming for about 25 years. Also Crash Bandicoot(XBox) she loves that too.
Help me out is Animal Crossing simple enuff for my 3 year old?
Of not what games would she be able to play, already got her Mario Kart DD and Mario Party 5.
