I've been looking for a suitable modern supernatural horror game for a very long time, and this one seems to be perfect! I've always found Delta Green to be too cumbersome for my liking, and Cthulhu Dark turned out a bit too rules-light, but Liminal Horror just hits the spot. Using ItO/Cairn-style damage for stress is such an elegant solution, it immediately clicked when I saw it.
I do have one slightest nitpick however. On page 8 under Connections the d10 table has "NPC" as one of the results, which to me seems a bit... redundant? All the other results seem to imply a specific relationship, so I've been wondering if that's intentional.
