Your comment is terrible for a whole lot of reasons.
1) Why would a price point ever justify piracy?
2) The game is "indie" only because it doesn't have a major publisher. The games been in development for several years and I'd guess over a million dollars have gone into its creation. Just because he didn't sign with Ubisoft to publish it doesn't mean it has to cost $15.
3) Piracy apologists are

ing stupid. You're right, not every single person who downloads it illegally would have bought it. But just because someone thinks "oh I wouldn't buy this" doesn't give them the right to steal it and play it for free. They're still gigantic

ing twats for doing so.
