I want to be like Beast when I grow up... Except the Real Madrid bit.
But yeah me too, I've been loyal to PS1, PS2 and now PS3.
I would suggest that you get them a Wii because it's great fun. There are some great titles, and although you have to dish out extra for some of the apparel, it's worth it. For example there's Wii Fit, for which you have to buy this board thing, but the mini-games are great fun, and it's probably the "healthiest" form of video gaming. And then there are some great sports games, the usual 'cute Nintendo' titles.
I'll always prefer the PS3, but just to demonstrate the 'power of the Wii' - my parents had never played video games before in their lives, but when we got Wii fit my dad started playing while my brothers were asleep and even my mum tried a few times.
