Wi and 360
I have a Wii, use it almost every day. Mainly, I play wii sports (I play for beating frustration, and exercise) Friend has had a 360 since they came out. We took our wii up there and (friend+wife) wanted one. They finally found one, and also got wii fit.
The Wii gets used every day in their house, both fit and sports. Their 360 mainly gets relegated to a rare game of assasins creed, or GTAIV, it's main use now is for when we come to visit, to get drunk and play rockband.
Of course, I also had a gamecube, so I had games for that. I also have kids (4, 6 and 11) so the Wii's also better for them. Before this, my last console was a Playstation, bought in early 96, and before that, a gamegear.
I know I'm not the core demographic - I like innovationa nd gameplay, so thats FPS games right out (they've not really moved on since half life or Quake). My favourite game is GalCiv2. But yes, if you're of the 15-25 male group, with a short attention span, then yes, the Wii won't be played much, it's not a system based around graphics.
Ctrl+alt+Del has the xbox owner pegged just right with Ethan. A shallow immature young male, easily distracted by the 'next big hype'.
Must dash to the wii though, I'm late for a game against brokep...
