Beyond that, what does it even matter if a species changes the genre? It'd still be a great option to have, and there are plenty of sci-fi games utilizing a version of the 5e ruleset.does it though? what about wookies themselves change the genre? i recognise they come from a sci-fi home media but it's not like they inherently drag their native tech level with them if transplanted into a DnD world, is a wookee all that more out there than a minotaur or an orc or a firbolg?
unless you're talking about the idea of transplanting an entire society into the world suddenly which is just an issue of perception, that this species is just 'popping in' en masse to a world they didn't exist in before.
