This half-physical-set (半实景) game is also available in China, so Chinese reviews exist; you might want to check them out too.
Played at: 忆南馆谋杀之谜 / 忆南推理馆
6 characters (2 female, 4 male)
《二律背反》is a fascinating “half-physical-set” (半实景) case. It has a hefty amount of content (~6 hours’ worth, when we played) and a complex structure worthy of a tabletop case. But instead of reading clue cards, you search the scene for physical evidence, which you then interpret.
Most interestingly, unlike some physical-set games where you just ransack rooms, the placement of each piece of evidence is significant.
Case: This ambitious hardcore case covers all the usual types of deduction: figuring out identities and relationships; reconstructing specific happenings based on evidence and timelines; piecing together a broader story; and exploring the world’s overarching mysteries. Granted, the plot goes to some strange places in the final act — but up till then, 《二律背反》is an engrossing exercise in reasoning.
Suspects: Due partly to the nature of the case, there’s limited immersion, though certain revelations might still be emotionally effective. Some roles are more important than others, but there aren’t any truly sidelined characters.
Structure: This multi-stage, multi-layered case requires at least as much stamina as a tabletop one — perhaps more, given the added dimension of physical scene analysis. There’s a build-up to a narrative and deductive climax, and a thorough epilogue.
That’s the core experience; what about 忆南馆’s specific implementation?
Setting: I suppose this is technically part of the game specifications rather than the implementation, but: by far my favourite aspect of《二律背反》is its use of physical evidence. For me, this alone suffices to make the game worth playing. It’s not just the fun of handling real evidence; what I really appreciated was the inclusion of clever details and subtle significance of various clues. The actual setting isn’t that impressive, but that’s in line with the plot, so nothing to complain about there.
Facilitation: Our DM saw us through the case patiently, asking the right questions to get us unstuck without giving too much away. He was also quite generous with the ending, haha.
Try if you like: Ambitious and unique game formats; interpreting physical evidence; rigorous in-depth analysis and deduction.
Not recommended for: Beginners; players uninterested in working out detailed strands of logic; players who dislike unrealistic elements.
