People are offering to pay as a hyperbole to try to tell Activision how much they want to disable the skins. Nobody actually is willing to pay extra for that. Its like dangling a carrot in front of a corporations face.
“We want to do X so badly, we are willing to pay for it,” which translates to " We want to do X so badly, we are willing to do the last possible option that we want in order to be able to do X."
World at War was the best one, what do you mean?
Though I stopped at WaW, then played Advanced Warfare (which was cool I guess), Infinite (which I actually really liked), and WW2 (which was honestly pretty bad especially by comparison to WaW).
