The future of gaming is in the market. Recently the market decided to go crazy over many great indie titles such as minecraft, limbo, braid, fez, meatboy, bastion, etc. These games offered new gameplay concepts that the major publishers ignored because for decades they literally got rich doing the same thing over and over again. Gaming has recently had its market explode in size. Publishers will be looking to copy successes, whether it be an indie success or a AAA success. Many genres have plenty of room for innovation. Simulation games for example haven't had any real innovation since Maxis was in its prime. I will give Poptop software some credit for Tropico but it hasnt really seen big improvements since the first title. Tycoon games are a shell of Rollercoaster Tycoon (the originator) nowadays and only offer a small portion of what Chris Sawyer gave us. Strategy games have seen some new ideas in the turn based area, but the real time strategy genre hasn't seen a whole lot of innovation. Action games and shooters have seen a lot of streamlining.
With the market quadrupling in size like it has recently, now we have to wait and see what people support. AAA games will do what they have always done and try to polish and streamline the successful ideas. Indie devs will continue to do what they have done and try to do the best with what they have to work with (which is much more nowadays). SO the market is not only bigger but more balanced to give everyone equal opportunity in the market. With this generation being so slow out of the gate, its possible that many will drop out of gaming and the status queue will stabilize back to the tried and true method. However, it is also possible with the success of indie games recently that the market could see a big shift. Thanks to Skyrim and Witcher 3's success, we may see a lot of RPGs flood the market. I don't think any industry position really has the market cornered right now. It's anyone's ballgame right now, and hopefully I hope stuff simply stays that way indefinitely. It would be awesome if at one point in time so many good games release that it is impossible to keep up on everything.
