As I look on games and game talk today, I tend to pick up a lot of what "the next big innovation will be" discussions. Everything from VR helmets to implanting games in your brain. (me and my friends come up with some ridiculous ideas)I tend to feel like we should look to some of the innovations of the past to find out what we can do for the future. So tell me, Escapists, what do you think was the innovation that had the most impact on games as we know them today?
