There are a lot of different Carcassonne expansions available and I'm curious if anyone has any insight in to telling if combining them may break game play? Recently we've been using Inns & Cathedrals with Cult, Siege and Creativity. It seems to have drastically changed the balance so that it's very dangerous to try and build a city of any size. Most cities end up being 2-3 tiles, putting a ton of them in the field and sieged cities make being a farmer even more attractive. Last game, every big meeple was a farmer and three players had 5 meeples each in one large field.
Is there any general advice on combining expansions? Are we just experiencing different game play thanks to different tiles?
