So, all other clients (IW4X, T7 CleanOps, and others) let me play multiplayer on pirated copies, but Plutonium won't let me play Bo2, even though MW3 and WaW worked fine on it with pirated copies. And no one's asking you to upload the game directly to your website; this is a complaint about the purchase. (By the way, I don't understand what $20 you're talking about when games on Steam cost $60.)

That's all.

Am I correct in understanding that the super-intelligences who created this client, for some unknown reason, are forcing me to buy a 2012 game for $60 just to play multiplayer on a third-party launcher? If you're going to make a third-party client, please make it publicly available. No one will spend money on a dead game.
