I think the gaming market has hit a renaissance since the launch of Kickstarter. There are so many great ideas that have been floating around for dacades, but due to lack of funds, never got to see the light of day. When I attend conventions, I often see monolithic blocks of game tables dedicated to Pathfinder or D&D, but more and more I see pickup games of indie RPGs going on in various corners. Just like the internet brought variety to the music scene (instead of big record labels having a choke-hold on what you are exposed to) I think the internet has had the same effect on RPGs. Incresaingly players know more and more about alternative sources of gaming.
It's easier now than ever before for a basement operation to make it out of the underground scene. With print on demand (POD), there is no longer a need to succumb to archaic print runs and supply chains. And from a designer's standpoint, its a veritable pleasure to pick up more games in digital format (more than I can possibly play, and no need for real life bookshelf space), but instead just for the pleasure of reading a great design or creative idea.
The PDF rennaissance (and the associated OGL boom of the early 2000s) seems to me to be just as big, if not bigger. Basically, it's a growing trend (not just in gaming - people have YouTube TV channels, podcasts, all sorts of things) of removing the middle-men and creating/marketing/selling direct. 3D printing's gonna get big soon, too - that'll affect the minis and boardgaming industry massively when all you have to sell is a blueprint. Who knows what else is coming? I think Kickstarter is one thing in a line of things.
