My kids are 2 and 7. Been thinking about getting Wii Just Party but haven't seen it in action. I do worry that I might buy it then fret over some of the moves being too sexy and not suitable for kids. Am i being silly and worrying for no reason? Any thoughts on if we should or shouldn't buy. Also does anyone know if Just party 1 is different to Just Party 2? Whats better and why?
