... there's a thread on r/rpg where someone basically says:
* They have a group that played D&D
* Group wanted to play something else
* One player opted out and said he didn't want to play something else, so he should leave the group
... and OP is asking 'should I try to bring them back even if they don't want to play the new sci-fi thing?'
JUST
FUCKING

PEOPLE
