I wonder if WotC wants to create a "isekai" line. This has got its risks, because adult people from this world in a fantasy realm if they survive enough, they could start the industrial revolution.
Othe theory is the new world being created to allow crossovers with no-fantasy franchises, because Hasbro likes to sell licenced products.
Urban Arcana as a TV show? It may be a superhit or a bomb if the productin is right or not. But we know nothing about that old UA a lot of time ago. Urban Arcana as videogame? Why not if there are titles based in Shadowrun? Urban Arcana would be technically "reverse isekai", wouldn't be it?
