By that I mean games that are either out-of-print, impossible to buy, region specific, or impossible to play on the source. My stance is that I'm fine with it, because however you buy these types of games, no money is going to the original developer, just to some cheapskate trying to push you into buying old merchandise. And if no money is going to the people I want to support, what's the point in even going the legal route. At that point copyright law is just being a bitch
