Why is ground war, and the number of players it attracts, only on the x-box one?
You must spend $500 to play Groundwar on the biggest maps in CoD history.
The amount of players in the match. Thats why.
Heck I remember in MW2 I think it was where the lag was worse in that game mode than any other game in history.
MS must shell out lots and lots of doe for ATV to risk alienating the PSers.
