All of these are connected, and much more essential to the long term health of the industry than "Microsoft leaving the game industry" or "Nintendo going third party," which, in reality, are self-destructive overreactions to problems with much more constructive solutions.
1) First, and most importantly, consumers hold publishers, developers, journalists, and themselves accountable for their actions. If you're sick of pre-order bonuses, stop preordering games. If a publisher mismanages its servers or releases a broken game, think twice before supporting that publisher with your money in the future.
2) Second, the establishment of a professional corps of video game critics. Video game journalism is hopelessly entangled, commercially and emotionally, with the industry it purports to review. Video game outlets urgently need trained writers and speakers who are free of influence from advertising money and committed to a code of journalistic integrity.
3) Third, fans need to grow up alongside the industry. Over the last 40 years video games have grown from a cult phenomenon to a significant piece of mainstream popular culture. I was proud to attend the premiere event at The Art of Video Games exhibit at the Smithsonian American Art Museum in Washington, DC. Nestled among contemporary and pop art, the exhibit signaled that video games could become a permanent part of a cultural landscape that includes the works of Chopin, Pinter, and Kurosawa. Yet, two years later, the industry continues to be plagued by an undercurrent of racism, homophobia, and misogyny, evidenced most recently by the ugly "GamerGate" movement.
