Are there any groups looking for more players, or any looking to start up in the San Antonio area?

Check out Magic Beans Cafe. Saturdays are primarily D&D 5e (bleh), but we do play other games for our 3rd slot (~8pm), and Star Wars RPG is one of them.

Is it Force and Destiny though, the last time I heard about something for star wars going to be run there the owner told me repeatedly that it was a sure thing then suddenly dropped all communication about it.
