We currently have a Gamecube that is still going strong, but I'd really like to upgrade to an Xbox 360. My main stopping point at the moment is the lack of games for kids, although there's plenty I'd like (Gears of War, Dead Rising, Guitar Hero). I have an 8 year and a 13 yr old and finding the right balance is tricky. Currently they are addicted to Phantasy Star and enjoy the usual Mario fare but apart from Viva Pinata and Kameo it looks a little bleak. Any ideas?
