Hi, thanks for the question!
The game is best suited for groups of players, between 3 and 6 with 1 Medium (GM) and the others as player characters. It is possible to play 2 player, but the other player should assume multiple player characters.
DMN is a freeform narrative game based around individual mysteries being resolved by the PCs by investigating a region. Play often requires a few hours setup time from a Medium. The game is suited to long campaign play with single scenarios taking between 1 and 6 sessions (3-4 hours) to complete depending on the pacing and intricacy of the scenario.
Our two published scenarios reduce the need for prep time and are built to last roughly 4-5 sessions.
We do have a discord for group finding here: https://discord.gg/SMXPccFEAX, but we are small at the moment!
