Xbox live that's what the xbox has, that's why any 3rd party online game sells like crazy on the 360 and the ps3 is ho hum. It's MS best product without a doubt until Sony can compete with that MS is going to always keep a large share of the market.

And yes the 360 controller it's just better for FPS, no one wants to buy a 3rd party controller just to have the sticks in the right place, and triggers rather than buttons.
