**** that, it's a crime and should be combated. I don't give two ****s about supply and demand in this context, but stealing is still stealing.
I can argue this on either moral or economic grounds. You seem to want to go the moral route, but I think you ought to at least know what the economic argument is before you dismiss it.
Consider...
(1) Not every pirated copy would have ever been paid for—but if it's a good game, they'll tell their friends about it.
(2) Not every pirated copy
wasn't paid for—some people get pirated copies of games that they also bought—either to try the game out or to bypass ****ty DRM
which decreases the value of the productIf you piss off the the group of people for whom (1) applies, you deny yourself free word-of-mouth advertising. And if you piss off the people for whom (2) applies, people either don't buy it because they couldn't try it, or they don't buy it because they know how ****ty the DRM is.
