We've played those maps.. in their context... which is where they belong. And many we have paid for as re-skins...
Let them give us ALL NEW maps in Ghosts... please. Stop begging for old stuff.
What they should do at some point is release a MP only version of CoD with a variety of maps from the multiple titles.
But let Ghosts be its own title. Stop asking for old stuff in new titles... it doesn't make sense.
