On the contrary, what we're actually seeing is an awesome increase in the number of non-European settings from writers and artists with non-European backgrounds. Just in the past year we've seen massive Kickstarters from an African-inspired sci-fi game, one by Native Americans, a big African-inspired setting book from Paizo, and a ton more. We're planning an awesome culture setting book for Level Up, which will be written by people with connections to that culture. On our podcast just last week we talked at length about the amazing stuff being made by creators from the Global South.Politics aside, I do think an unintended side effect is going to be an increase in European-derived settings as people try to avoid culturally appropriating from areas they don't have any connection to.
We'll see in 10 years...
It's pretty awesome.
