Actually, as bitchy as I am about pirating I'm fine with used and borrowed games.
With used games, you're still paying for them at least and the game is still getting a sale. That sale at least tells the developer it's still popular and people like the game. True, I would much rather you buy it new but I can completely understand buying used games. Buying used games is no different than buying second hand furniture or anything like that.
As for borrowing games, I don't have a problem with that. With borrowers, I assume it's between two people that both regularly buy games. Again, I'd much rather the person just buy the game but I completely don't mind people borrowing.
Now making copies, that is completely different. There's a fine fine line and that is crossing it.
