Clearly Xbox360 could play this game and it would bring in more Players . Because GW2 is F2P after you buy it , it could be marketted and sold on Live . The Gold Membership needed would not hurt the game because most Xbox players who play seriously on it are gold already.
I think it would be a great resource to have this game come out on Xbox360 and Ps3 .
Heck I played ff11 for years with keyboard and mouse on xbox360 so making a controller Program wouldn’t be needed but would be awesomely welcomed !
I know its a far cetched dream but just saying !
