I suppose this is karma of sorts, but I just found out that my paid version of Spades is showing up in a bundle of games on one of the popular torrent sites. I suppose on the one hand I should be somewhat flattered that my game is considered decent enough to pirate. On the other it kind of sucks.
I'm not going to rehash the old piracy debate. I've heard both sides and I'm not sure whether I'm convinced that it really does hurt legitimate sales. My Spades sales are virtually zero these days, but I attributed that to competition from a rival Spades app on the market. It would be interesting to know if piracy is negatively affecting my sales, but I'm not sure there's a viable way to quantify the effect.
