Ah, vineyards! Lovely element. Like an Inn for a cloister. Sort of. It's nice that they've got round to introducing that, a simple way to bump up a few points on a cloister. And multiple cloisters, if you're clever! And multiple vineyards, if you're really clever! Interestingly, no penalty for a vineyard. You don't score points for a vineyard on an incomplete cloister, but you still score endgame points for the cloister, unlike inns and cathedrals.
I really like vineyards. It's a simple addition, nothing confusing. Thanks to BB5, I have two copies of the vineyard tiles. In large games, I often add two copies of Inns and Cathedrals to balance out the increased number of tiles. I may start doing the same with these!
