One other thought - it'd be nice to have a physical games section on the itch Discord.
Please direct any additional feedback to the Feedback and Questions thread in the forum.
Splitting by system seems counterproductive.
Where would OSR games go? Into a D&D category? That assumes all OSR games are d20-based and-or retroclones of D&D, which they are not. Split across multiple subforums? That fragments the OSR scene and disincentivises us using the forum.
PbtA is also a nebulous category. Monsterhearts is nothing like World of Dungeons.
It silos off interesting ideas from each other and disincentivises breaking the mould. Some of the most interesting work I've seen lately are PbtA games adopting OSR ideas, or an otherwise OSR game adopting a mechanic that drives narrative toward a predetermined outcome.
If people are making OSR games, there's an OSR subcategory here.
Monsterhearts is nothing like World of Dungeons, true. If there's a huge disparity and we need more space for growing subsections, we can make them. This place has existed for a few minutes. Give it time to exist so that we can see what we need to change or alter.
Rather start with my personal mental map of "gaming" I thought it might be useful to look out at what RPG communities people joined in Google+, both because I think the self sorting gives interesting insights, and because G+ has been very important to the RPG space., and it is going away, leaving a gap. Here's a list of most of the communities over an arbitrary 2000 count. (I stopped bothering for the last maybe a dozen D&D groups I encountered)

My read on this is that people rally around games systems and publishers, but that there are probably a few topics that could be a productive seeds for "system neutral" discussions like "Game Master/Tips and Prep" or Tabletop Podcasts and Actual Plays.
It seems clear that we need spaces for a Fate, Power by the Apocalypse, and OSR both based on the popularity of their G+ communities, and because lots of indie creators build these game around these three categories. For example, I have a Fate based game here, and importantly, Evil Hat, the creators of Fate, are selling their games here. Have any other major indie publishers done that?
It might be useful to have a D&D forum, even if Wizards nevers sells here, so that the 80% market share gorilla plays nicely by itself, and doesn't accidently stifle other conversations accidently.
It probably worth considering what the big three "generic RPG" communities had as categories. At the the very least, that way of breaking things up didn't harm there success.
If someone had expertise on the LARP or boardgame side, it might be nice to undertake a similar stab at the data from those communities.
Not data driven, but conjectural based uniques nature of itch, it probably makes sense to have
I'd be willing to help out with moderation, if you need more people to pitch in. I professionally managed a 2000 member forum as part of my job responsibilities for 5 years. (Of course, the community consisted of mostly middle aged women who lead small community based healthcare programs, who were fierce and focused, but in a different way than many gamers, so I'm sure there would be plenty of things to learn by doing,) Beyond playing and designing and discussing) TT RPGs, I play a fair bit of boards games (but don't hand out on board game online spaces and have play some LARPs, even they are a huge hobby focus.
