Developers and publishers are facing more and more difficulty to make a profit from games, leading the industry into the path of very questionable practices like in-disk DLC, microtransactions, in game ads and etc.
But, I think there`s another way to work this problem. Allowing publishers to sell games with a higher initial selling price may lead the industry back to the way it was some years ago, the games being full experiences by themselves and DLC really adding worth content and not just selling chapters that were cut off the main game.
Actually the 60 USD price tag is relatively new and exclusive to NA. Europe has games being priced at 70 EUR for big releases and in Japan hot releases may sell for the equivalent of 100 USD. And even in NA it wasnt always like that, back in cartridge era it was common for games to be priced 80 USD or more depending on popularity.
