It would probably be a bit easier with Daggerheart than 5E due to the PCs being built with backstory and connections as the default. Threatening those is a quick and easy avenue of horror. Overwhelming monsters is easy in any system, in Daggerheart just ignore the suggested combat math. The lack of darkvision makes things a bit easier.I've done effective horror with D&D, so I'm sure I can do it with DH.
