We have got loads of games between the 3 of us - Cooking Mama, Touchmaster (great game - my favourite), Sonic and Mario at the Olympic Games, Sims 2 pets, my Vet Practice, Yoshi's Island, Disney Friends, Build a Bear Workshop, Scrabble, Super Mario, Brain Training.
To be honest, my favourites are the platform games but I also like Disney Friends (I'm just a big kid at heart

) and Touchmaster is great - it's a compilation of lots of different card, board and puzzle games.
