First time playing?
Recommendations for how to get started:
Begin with a solo game with just the base game + Wessex to start (Wessex uses the same ruleset as the base game). Solo teaches you the flow so well, without the bother of teaching someone. Here's a new video series showing solo with 2nd Edition Obsession, very well done:
Then play a 2 player game, again just the base game + Wessex. This makes the 'teach' easy and avoids downtime with higher player counts. Be sure to play with a Closed Courtship (explained in the video below). Here's a playthrough with just two players using the base game + Wessex:
Then onward to Upstairs, Downstairs!
