I love Classic Deadlands.

Oh my God does combat drag like hell. Everyone can have multiple actions each round, up to five, and everyone draws from the same deck except the gm, so if you have a lot of people, you are drawing like half the deck each turn so chance for that black joker goes up.

But the setting? The roleplay??? Where's the heart eyes emoji. That shit is my jam. I miss you, Jewish Blessed trying to track down a golem he made. You were a good character.
