most of my friends play cod on line on xbox thats why i first bought one
when we all started having kids we swapped nights out for beers at home and giving each other shit online
We're in the same boat. I loved my PS2, but was given an XBox by a co worker. End up watching baseball games while being on Live! with my brother who lived cross country. It was like he was there.
Then, kids, and lots of multiplayer interaction. Most of these guys are hardcore gamers - they mod/import games from Japan/ know all the industry stuff, and they will get all the consoles. But they mutli on Xbox, so that's where I am.
