This is like going up to an aspiring writer in ancient Greece and saying "The Odyssey has already been written, there is nothing more to be done." Not realizing that 2,000 years later, authors like Joyce and Nabokov would still be breaking new ground.
Assuming the human race endures long enough, video games are at the very beginning of what is going to be a very long and interesting history.
Star Citizen is the only thing on the horizon that shows promise, at least to my personal tastes.
Best of luck in your endeavors.
I do think there is some possibility for innovation in gaming with AR/VR, but I also agree we've probably reached the point of diminishing returns with what we can do with current control schemes (monitor + mouse/keyboard/gamepad).
The highest level of gameplay involved very little spreadsheet hell and a lot more skill, leadership and coordination that one might think originally if they did not have a strong corporation to align with. It's true that there a LOT of numbers behind the gameplay that you had to consider, but spreadsheet hell was a result of poor UI/UX choices and not necessarily of game design.
If Star Citizen can replicate that, but with better graphics, and personal ship control (instead of EVE's point and click) - they will already be a success in my book.
