Most "best board games" lists rank by quality. That is not the question at 8pm on a weeknight — the question is what fits the people, the time and the energy in the room. This list is sorted that way.
The Crew, Codenames
Needs to pause and absorb an extra player without resetting.
Azul, Cascadia
Short setup, no rules refresher, done before it gets late.
Codenames, Azul
Rules explained in under three minutes, no reading of card text.
Brass, Ark Nova
Worth the teach only when nobody is watching the clock.
Weight is how hard it is to teach, not how good it is. Two of the heavy ones are our favourites and still barely get played.
