I know my opinion very much in the monority, but Agricola is not a good game. When it came out, I was so excited, but the game did not deliver. There are two things that ruin it for me. First, blocking actions are sometimes nonsensical. For example, you built an oven, and I build an oven, so why does your baking bread stop me from doing the same? Second, the scoring in this game is such that you typically have to do a little of everything with only slight specialization (often directed by the cards you draw). I played several times, hoping I would learn to love it, but it was always disappointing.
Now, since then, I have played and very much enjoy Rosenberg's later, similar games. Caverna, Ora & Labora, Nusfjord are all excellent. At the Gates of Loyang is quite different in a very good way. Fields of Arle has become one of my all-time favorite games. With all these fine choices, I am quite set to never play Agricola again.
