It's been proven again and again and again and yet again that pirates are not lost sales as they wouldn't have bought the software in the first place. Those who have no money can't pay so they pirate. This has been proven with those thieves at the RIAA/MPAA who send out masses of letters to random people in the hope that even 1% will get scared and settle out of court they've made a killing. Now anyone wanting to claim that pirates are evil can go to the poorest of countries and tell those people who save up for years to buy a PC that they are evil as their poor, starving, destitute corporate overlord can't buy that third or fourth private jet, yacht, island or nation.
For example, Batman Arkham Disaster doesn't interest me and I won't even pirate it as I don't feel it's worth the time. Corporate liars will come out and make up random numbers that the game (if that is what you can call that bug fest) was pirated a million times and even include non-sales like me.
