I am happy to say I bought a WII (already own it tucked upstairs) for my kids to christmas. I have played the WII over friends house so I am pretty familiar with it I wanted to get them some games and wanted your advice. The kids are 10 year old boy, 7 year old girl and 5 year old boy.
My thoughts were
Super Mario Galaxy (they love sunchine on there cube)
Super Smash Bros BRawl
PS3, WII and 360 all great systems depends on what type of console player you are.
Currently playing Call of Duty Modern Warfare 2, Fallout 3, Halo ODST and Dragon Age Origins is next game
