Minecraft already took a huge chunk out of the industry. Which they then tried to solve by encoperating this and selling additions.
Now another game appears, that offers endless replay ability with fascinating stuff. If the onslought would be kept up, all those monetization schemes could collapse over time, by virtue of simply being boring compared to what the "indy" dev scene has to offer.
One starts to wonder, what could happen if a concentrated efforst started churning out ever better world generators and "deep" games, allowing others non "deep" players to join the world just as "action" heroes or adventurers.
