I think the underlying question here is: If someone were to create a game that used the same basic mechanics as BOB but wasn't themed around marginalised groups establishing an independent community, then what should they refer to it as?
(And if that's not the underlying question here, I'm still interested in the answer. 🙂)
On one hand, it wouldn't feel right to call it a BOB game. On the other hand, it wouldn't feel right to not credit BOB as an inspiration.
Would you just call it "A Belonging Outside Belonging-inspired game"?
