Well DM'ed game, not too heavily narrated gives players time to think through options before deciding.
Good pace, both inside combat and outside combat.
Explains any homebred rules in discord chat (in clear written text) to avoid confusion.

Good pacing, excellent management of players, everyone got to speak and take turns, runs a good story with depth
Samuel Foreman
GM created his own world and adapted it on the fly, to every decision I made.
He was never stuck for ideas and had a clear idea about how different elements of the world / one shot fitted together into a coherent whole.
