Hiya. I haven't been in the community for long, but I thought I'd offer my insight on the topic.
I downloaded RenX long after I joined the community. When I finally tried the game and found it wasn't really my thing, I still stayed for the community (specifically, the Discord community). The RenX Discord community seems to be one of the friendlier C&C communities on Discord, and I've been in 4-5 so far.
Hence, I agree with this one. Having a strong community is a very important asset to have because of the next point.
Pros and cons of having a niche audience. While the traffic is small, it is easier to cater to said audience. So, who are we dealing with here? Nostalgic C&C players who either like old school Renegade or want to play a C&C FPS. How to cater to this audience? If you ask me, a short term thing can be focusing on getting players on board the game, because RenX is a traditional FPS, not a modern one. There's a lot going on in an average match, so bringing players up to speed helps. I heard Kira mention a WIP tutorial map, so that's great. In games such as Natural Selection 2, I found the community wasn't too friendly with green players(i.e complete newbies), because that game was also a RTS-FPS hybrid with the commander figuring out which upgrades to first, has an overhead view of things, etc. I had to rely on a friend to hand-hold me throughout a match because I had no idea what I was doing, and constantly died. I stopped playing after that one.
Long term steps can be giving C&C players more of what they want. It may take a while to figure out what works, but an example could be adding more lore bits, because any game in the Tiberium universe has lore as its biggest advantage, that is the reason why that universe still has a following to this date. Existing stuff that's good are map descriptions and little easter eggs here and there.
Better interaction with the community does help. A post about the upcoming PUGs, and another post just before PUGs begin with a Discord link can help. If you look at the Facebook page, even non-RenX stuff gets traffic (simply because C&C fans like to talk about anything C&C-related, so I'd suggest capitalize on this). I can vouch for this because I did have a Tiberium Tuesdays segment running for a bit, some of which were re-shared by Twisted Insurrection's Fb page. I covered multiple topics in the C&C-verse, so when someone talked about a topic I wrote about, I just link it to the chat and it becomes a conversation piece.
Summary:
1) RenX's biggest asset(if you ask me) is its community, the Discord one to be specific.
2) The target audience are C&C players, small yet niche.
3) More frequent posts on the Facebook page would help improve interaction with the community.
That's about it from me.
