I have a little tiny bit of personal and professional background concerning Dziria which is a minority language in the Franco-Algerian diaspora, but there's something like three thousand languages and hundreds to thousands of ethnic identities on the continent so there is probably a lot of learning (to put it mildly) that be done to better understand where the continent might be and what the culture might look like 85 years in the future.
I think it would just be cool and interesting if players thought up ideas or shouted out things that they think would be cool inclusions, media they think might be inspirational to draw on (I'm really not read well enough in Afro-Futurism and would love to get recommendations!), or just general crowd sourcing of new ideas to fill out potential details.
So if anyone has suggestions or ideas I'd love to start a discussion about them. For example as a way to kick things off, the Grand Ethiopian Renaissance Dam is a megaconstruction project that has the potential to completely transform the region if completed, and might be an interesting thing to develop into a story.
