I have a Xbox 360 and Nintendo Wii. I feel the Wii is more for kids and rarely play on it. I only ever use it for BBC iPlayer now and if that goes on the Xbox then the Wii will end up being sold.
I've only got a gaming PC and one of the new Xbox 360 Limited Edition elite (250Gb), but tons of games, and I'm loving it.
Nintendo 64 Playstation 1 Playstation 2 Xbox Game Cube And Xbox360 My favourite is the N64 for nostalgic gaming, the the xbox360 for hardcore gaming.
I own almost everything since Famicom. I took care of it. I don't play with it anymore of course but it's just great for keepsakes.
