They won't catch you since I doubt they're trying. As long as you don't make a lot of copies and try to sell them, no one will care.

And you know besides all this, I know people who consistently pirate games, movies and whatever. Yet they still buy quite a few of them. Legit copies that is. People want to buy the good stuff anyways.

Besides, I would find it ironic to call something like a GTA game as "intellectual (property)". I say pirate crap, who cares!
