If you ever end up hating D&D because it went too mainstream, the old D&D you knew and loved is...on DMs Guild. It's increasingly offered via Print-On-Demand. And what's even better is that they can't ever take back the SRD, so except for 4e, people are still making content for that old-tymie game.
Yeah this is huge. The 'doing it for the art' is still very strong because of this. D&D itself may (will) shift and distort itself to make sure it doesnt run afoul of anything that could limit its customer base, but people still have the framework to build upon.
