I tend to play with the River and Inns and Cathedrals. We also play with a house rule that you have a hand of 3 tiles to alleviate some of the draw-dependence of whether a strategy is successful or not.
Oh that’s a neat rule, I like that! It’s another level of strategy that you wouldn’t normally get. I can see it being fun in smaller groups, because there’s less to keep track of compared to a 5-person game
