Current favourite boardgame is Hallertau, a slightly more complex game where each player manages a small Bavarian village in the Hallertau. The Hallertau in Bavaria, Germany is the largest continuous hop-producing region in the world and it prides itself upon being the first in Middle Europe to cultivate hops. Your objective is to increase its wealth and prestige by supplying the local crafts folk with goods from agriculture and sheep breeding.
There's a quite a lot to manage in this game. Most of the decisions you make will be where to send your workers during your turn. What do you want to do? Plant different crops or breed sheep or buy tools? There are about 20 such choices waiting for you. You will also get to draw cards that will give more resources at a cost and even affect the decisions you make. I know it sounds cliche but it's one of those 'easy to learn, hard to master' kinda game. By gaining specific resources like barley, milk, wool or hops, you get to move your community centre and score points. The trick is in managing all your resources, knowing how and when to get those resources.
It's a really amazing game and one I would recommend to anyone looking for a good boardgame challenge.
