From 20th of November to 2nd of December 2019 Navigraph is conducting a FlightSim Community Survey together with several major addon developers and organizations within the flight simulation community. The survey, the largest of its kind, aims to gauge the prevailing flight simulation trends and users' requests for future development.
It is mostly aimed at the civil-aviation simulator market, but DCS, etc. get some mention too. It also considered hardware, future wants and lots of other things. Pay attention to the categories... you might find some good names and references there, if you are interested in the genre and are wanting to expand your horizons a bit.

Results are posted as open-source for each year too: (example 2018). So, even if you don't want to do the survey, you might like to see the results from previous years.
