From the official description:
Our Brilliant Ruin hones in on the relationships and drama of class-based society and the balance between the haves- and have-nots. […] Players must navigate the social and political machinations of a class-based society while facing the end of the world. Three distinct factions and the families and guilds within them allow players to create fully realized characters to inhabit this doomed world. Investigate an abandoned mansion fallen into danger and disrepair, attend a high-society ball while keeping abreast of the ever-present danger, or confront a deadly chimera that bears an unsettling resemblance to a missing lover. The world is an open book of possibilities… until it ends.
It might sound silly at first blush, but you must understand that this would not be the first time this time period has been adapted successfully into a TTRPG. Shows such as Our Flag Means Death and Bridgerton helped pave the way for games like Good Society: A Jane Austen RPG and Lady Blackbird, two of the eight scandalously good period fiction games we recommended in 2022.
At least it’s not another hack of D&D 5e
At the higher budget level, where basically the products can afford plenty of art, I basically never see games using the 5e engine? Perhaps I’m wrong here but beyond the splintering of many of the companies that previously made 5e content like Darrington Press, MCDM, Cubicle 7 and Kobold Press, I don’t think I’ve seen any non-amareur RPGs based on 5e on the horizon.
I do see a lot of powered by the apocalypse game, and within that a few forged in the dark games, but powered by the apocalypse is so varied anyway that I don’t see it as an issue. I also see Freeleague using the same engine for their games but that’s a specific company using their engine.
