The irony of all this...as a 44 year old gamer who's been an enthusiast since my Dad took me to an arcade where we played Robotron and then eventually found an Atari 5200 on a Kmart Blu Light special....is that as this industry has changed, it's gone from 1 power player to 2 power players to now a handful of power players. In the next few years as barriers to entry lower and reach becomes easier, there's going to be more options and ways to reach consumers ever before. More options for consumers. More competition. More demand for quality content and pressure to offer value.
Yet even as the industry has drastically changed, gaming is the one that continues to do the best job supporting nostalgia. I own an arcade stick and can download most of my favorite past arcade games pretty cheap. There's still strong 2D games getting made...arguably at a better clip than when 2D was the only option. Outside of the deterioration of the social aspect of gaming, everything else has been maintained and then built upon. Forms of distribution and access change but the content evolves and expands. Now game preservation is more of a focus.
In the end, just be concerned about consumer rights and value. Gaming is not an industry in danger of consolidating it's creatives anytime soon. As long as the demand for creatives is high and there's good value for consumers, the industry isn't on the brink of disaster.
