You know, if the gaming industry goes down from piracy, then they've obviously goofed pretty bad with their salesmanship. Anyone is going to steal anything if they want it bad enough, but if more people are stealing an item than there are people buying it, that usually means that the industry isn't marketing their products well enough.
If best-selling games like Skyrim, Portal 2, Deus Ex: Human Revolutions, or other games sold for $30 or less, instead of $60, I'd guarantee that there would be a lot more consumers and a lot less pirates out there. The amount of money earned from sales and investment returns would be more than enough to earn a fairly hefty profit for the producers and developers of the game.
But since gaming companies insist on making these games unreasonably high-priced, people are going to want it either a) pre-owned or used for a better price or b)they're just going to pirate the game to see if it was even worth its pricing. Which, in my opinion, is rarely ever the case considering I could fill up my car completely and be set for about 2-3 weeks off of the money I could risk on buying a game that may not even be worth the hype.
It would also help if the gaming industry was willing to take more risks and actually listen to their targeted marketing denominations instead of playing things safe and going off of what's been easier to do in the past. I'm more than certain that plenty of wonderful game designs and ideas have been shot down by major gaming companies because it wasn't something they were 'comfortable with investing in'.
