First of all, thank you very much for giving our game a try as your first ever tabletop RPG! We hope you were still able to enjoy it even though it wasn't exactly what you had in mind! We did purposefully write the game to be open ended and up to how each player decides to attribute meaning to what they find - but we are aware that may not be everyone's cup of tea!
Still, if you'd like to play a game using the same base set of rules (but giving them its own particular twists), with similar mood and references, but with more definitive outcomes, we couldn't recommend Lari Assmuth's "A Weekend In The Country" more!
