My father tried something similar on me a couple of times. BIOS passwords, since every game we owned was Warezed, no discs to steal. Of course, getting past a BIOS password is easy (screwdriver, J21, done) but it cant be done tracelessly, which got me in serious trouble at times.

I know what I would do in your situation, but most of it would just make things worse. Best thing I can recommend is to forget your remaining games (stands to reason they'll dissapear if your stepfather finds em), study as hard as it takes to get a better economics grade, and when you move out leave an itemised bill on the table. Theft is theft, whether the law says he is allowed to take them or no. But whatever you do, dont get angry (or at least dont act angry).
