@titania We can go even more afield into #TTRPG obscura.
#ECH0 is an odd little game which involves GMless storytelling and map creation but does really want either one-on-one play or three or more players, which may not be a problem or could be depending on how you foresee playing these games. It's extremely lightweight and has a very specific sort of mode it intends to be played and but – we are creative people.
It's definitely one of the more unusual examples of the genre.
