Call of duty ghosts= Bastion?

So i was watching the call of duty ghosts cinematics, then it hit me that bastion and ghosts have similar premises:

The Ultimate Weapon of a nation (the multi missile launcher satellite and the calamity) is used against itself resulting in an apocalyptic land with young boys guided by old men in order to restore some life during the apocalypse aftermath. And they acomplish this by using (yet again) somekind of ultimate weapon (the bastion and the copied satellite on ghosts)

Have you seen similar plotlines on another games or is it just me seeing similarities?
