About half a dozen one-shots with a group... I can only remember Dungeon World and Dogs in the Vineyard...
Aside from that it was:
My own supers game
A little Star Wars
And... I can't remember for sure when my Blue Rose game stopped. Might have been the very end of 2018, not the beginning of 2019.
Of Those, D&D and Numenera are the top two. Numenera was #1, but D&D passed it in 2019.
