I think out of Agricola, Gates of Loyang and this, Le Havre might still be my favorite Uwe game. All three games have similair mechanics to them, but there is just something more forgiving in Le Havre that makes it appealing for me. Again, it's one of those games that is incredibly simple to learn and play, but extremely in depth and rewarding to discover once you decide your path and follow it to it's end game.
Masterful and Unique. One of the most complex games I have played in terms of strategy, yet has some of the simplest mechanics and gameplay to learn. It's one of those off mixes of perfect gameplay, simple to understand rules, but extremely deep strategy. One of a kind.
