I dunno if this is strictly hot-and-new but a thing I've been picking up on lately is a growing contingent of OSR and post-OSR developers (e.g. Zedeck Siew and the team behind Sundang) putting forward some actually pretty compelling arguments for largely discarding the conceit of "genre emulation"—it's an oversimplification to call it a "simulationist revival," I think, but it feels like we're approaching conditions where we might expect to see an explosion of dev work that, by wedding post-Disco Elysium sensibilities to post-OSR ones, ends up basically reinventing the design priorities of Traveller. Dunno if that's something you'd have feelings about but it's sure been on my mind.
