There is an upside to this, where some games will be released as partially complete, sell for a reasonably low price (none of that $60-80 USD nonsense), and get user feedback on gameplay and content as development continues for a few more years. Games like Minecraft and Kerbal Space Program both do this; they would probably be stuck in development hell of several years then become vaporware if they didn't sell before completion. (Incidentally, these are the only two games I currently own.)
