The deeper I get into this hobby, the more vibes become everything to me.
Vibes are just as important to a game as the rules. Rules moderate your story / adventure / experience as you tell / navigate / experience it, but vibes guide what everyone brings to the table before a single rule kicks in. A beautiful picture can inspire the mood of a whole session or campaign. The design of a pdf or even just an itch page can tell every player what kind of character to think up when called to. Is this a mechs with emotions evening, or are we descending step by step into a scary murderhole? Either’s fine by me, we should just pick ahead of time, and the Pinterest board the GM put together half an hour ago might get us all on the same page…
