This is so stupid, there is no encryption going on. The only thing that would be different about the warez edition and the actual edition would be the size of the executible, for MP you'd have to go down to a local store, open a box and rape up the cd-key. Well that cd key would legit, there would be no way they can say that cd-key is not legit becuz EA would know that it is a issued registered cd-key. So if info was being sent out, which it won't unless EA or 2015 was actually hosting the games online, then they would determine that the exe loging on is size, example, 5.09MB and the actualy exe should be 4.95MB, hmm, this is wrong why? Could it be pirated? Maybe, or perhaps a no cd crack is being used which in case they can't do much about it. The only fight they have on pirated version is using the right cd-keys thats it, and if for some reason durring the instal it has to log on to a server and verify you're version then you know you're fucked, but RTCW was not like that so I doubt MOH-AA will either.
my 2 cents
