I'd go underground,hide my gaming systems and games in false-bottomed,lead lined containers,with the decoy space filled with innocuous objects. I'd then play the classic single player games to kill time in short 30 minute stints,once per day. Games like "The Legend of Dragoon" and "Megaman X4". I'd use headphones while I play,to avoid suspicion via audio. Beforehand,I'd make a rep for myself as an avid reader who locks themselves in their room (litteraly) while they read. Also,I could lead a faction of gamers against this regime,with our sole identifier being having songs from video games on our music devices. This faction's sole purpose will be to subvert the Anti-Gamer regime by playing,distributing,and advocating use of video games,the Ghandi way.
Take THAT Jack Thompson,and the rest of you anti-gamer facists!
