Unless the game is played primarily online, the crack is as simple as spoofing the external authentication to create the local account. The only way this type of spoof won’t work is if the game requires constant real-time updates from an external server (i.e. wow or hellgate london or any other game that is played online).
As for high level encryption, what do you mean? You don’t need to know what data is sent, just the 1s and 0s of the data. If the data incoming from the server is high level encrypted when it is sent to you, then your machine can already decode it otherwise it wouldn’t understand it. If the outgoing data is encrypted then the trick is just to figure out which signal is the one desiring authentication. Clearly, you don’t have the hacker mindset.
