I find it strange to talk about D&D being too big given the small size of the hobby as a whole compared to other forms of entertainment. Personally, I think D&D is still just getting started and I'm more upset that WotC created this unnecessary distraction just as they were poised to break into the mainstream again in a much better environment for growing the hobby than the 1980s.
This is not a dig against smaller publishers and less popular games. Some of my favorite games make other systems look huge. I mean, Dialect or InSPECTres anybody? I can continue to enjoy TTRPGs in my little circle regardless how popular it is. Buy it was exciting to see what looks like a good movie come out, a TV series in the works, Balder's Gate III is exactly what I've been looking for in CRPG, and I've really enjoyed 5e and am have been liking what I seen of One D&D. I'm even guardedly excited about their VTT plans.
Then they had to crap all over it. Sigh.
