yep, that was my thought process to push for TTRPG (the tabletop part identifies as "something you play at the table" ), maybe "Tabletop + LARP" or use the "+" to identify as "there is more stuff related but we didn't knew how to categorize it".
It seems that there is no a super-easy answer (in certain light, this is good, this is a very diverse hobby even in outputs produced)
