My wife and I played Agricola and Lords of Waterdeep in quick succession, and I must pass along her observation: Lords of Waterdeep benefits strongly from having short term goals. Both are worker placement games, but scoring is radically different.
Agricola scores everything at the end, and everything is in play. You get a penalty for everything you did not do, a penalty for every space you did not use, and a variable number of points for each of nearly a dozen things. It is a complex balancing game, and it does not pay off until the game is over. Your long term plans could come together perfectly or be scuttled in the last round, sending you scurrying for Plan B or C. In many ways, it is the epitome of eurogames, where it is not over until it is over.
Lords of Waterdeep instead gives most of its points out as you go through the game. You get a few victory points for a few actions. You complete quests, each of which has a set cost and reward. You are not plotting out a goal ten turns from now and working backwards through reverse induction. There is still the big kicker of points at the end when you reveal your lord and get the quest bonus, but there is a feeling of progress along the way and of achieving small goals all the time.
Agricola is a strategic game. Lords of Waterdeep is a tactical game. The basic strategy of Lords of Waterdeep is to complete quests where you get bonuses, where the major sub-strategy question is to go for fewer, bigger quests or more, smaller quests (tip: “more” is usually better, especially at lower player counts). That’s about it. In a five-player game, you have only two actions for half the game, and you work on a much shorter time horizon.
Agricola definitely has appeal to the hardcore strategy player. Lords of Waterdeep tends towards a broader appeal with its playstyle and simpler rules. (And I have a friend promising to show me Caverna soon.) This seems backwards for their themes. Farming games have broader thematic appeal than Dungeons and Dragons, and farming has a seasonal reward cycle while I expect the lords of Waterdeep to be working grand schemes that only pay off after decades.
