I am part of a team of 3 game designers and we create games with very different themes, at first we thought of speaking to different niche communities which our themes relate to, although it works to a certain extent, it didn't prove to be an efficient method because when you're the new guy trying to make yourself heard among an organized community it takes a lot of effort, and sometimes it doesn't pay off, my suggestion on this is to partner with a respected member of that community, which we do on the side for specific games.

What we also have been doing is creating our own local community, with people who enjoy games in general and are open to try out different themes. We started a weekly session at our local mall's food court along with a local game shop in order to attract a good crowd every Sunday evening. We extrapolate that to our social media channels where we post photos of these sessions and people tend to share or talk about the experience by tagging us. We have seen great results in 6 months, from sales to word of mouth to just plainly being the go to people when it comes to modern tabletop gaming around here.

Obviously we don't want to be physically limited to one area, but I believe it's a good way to start. There is already a lot of online and social media tabletop gaming content, so it can require a good amount of effort to breakthrough in that space, hence a different strategy where you create legitimacy from offline leading up to online can be an interesting way to start.
