You know your famous when someone takes the time to crack your commercial game and put it onto a website where people can download it for free. I recently discovered that both Norilsk and LVN Fake News have been cracked and are being pirated. There's nothing I can really do about this, since this is the internet (and every game gets cracked eventually.) It's another interesting aspect about being a commercial game developer.

A lot of websites like this are based in countries like China. They don't fear legal action because legal action is not possible. These websites have games like Final Fantasy 14, I'm small potatoes to them.
author=Cap_H Bad news, which are also good news? It shows that your games are popular and that people enjoy them enough to put effort into pirating them.
