For PS2, my younger cousins (girls) like to play Super Monkey Ball Deluxe and similar mini-games collection such as Rayman Raving Rabbids. Eyetoy games like Kinetic, Sports & Play 3 are favourites too. Also, DDR, Dancing with the Stars, and similar rythmn games ... they tried to 'play' Singstar but they just bla bla bla thru the lyrics, so not fun for those who don't know the songs.
Anyway long time oredi didn't bring PS2 over for them to play ... didn't ask and I guess kinda grew out of it ... more into MapleStory and The Sims 1 & 2. Expected lor ...
