Terraforming Mars, Orleans and Marco Polo are all excellent games and in my Top 25 of euros. All of them offer multiple avenues to win and are engaging time after time. I especially like Marco Polo because each of the starting characters are so wildly different and each change the way you play. I would suggest the New Characters mini expansion with 4 new guys, but if your group doesn't care for it then there's no need.Had a couple of days off between Christmas and New Years. Made the most of them playing multiple games of:
Terraforming Mars with the Lexus/Nexus board expansions and the new Venus Next expansion. The Venus Next expansion adds quite a bit of goodness to an already great game.
Orleans. Really well constructed Worker Placement game that stays fresh given the number of expansions that are available for the game. Great artwork and very high quality components. Highly recommended.
The Voyages of Marco Polo. Worker traveler, dice driven game set during the age of Marco Polo. I really enjoyed the game mechanics but one needs to be comfortable with the range of variability in rolling 5+ dice per Round. The system worked well in my opinion, but that feeling was not shared by all of the participants. Beautiful board layout and quality components.
Great Western Trail. Awesome way to spend two hours driving cattle to Kansas City and then shipping them to points west.
I've said for the last few years that we definitely live in a Golden Age of board gaming and IMO all of the above games help reinforce that argument.
Other games seeing play included:
Ra. Always a great, relatively quick moving game.
NMBR 9. Highly enjoyable, super quick puzzle game.
Kingdomino. Fun, quick little filler game.
For those interested, in order to play a slightly quicker version, we played a three-player game of Terraforming Mars wherein each player controlled two Corporations at game start (1 Venus Corp. and 1 "standard" corp). Makes for a pretty fun TM experience as our game had final scores of 100, 100, 80+.
Also, had a chance last month to play 1914, Serbien muß Sterbien. Highly enjoyable experience with a pretty clean system that has much in common with the better aspects of MMP's GCACW series of games.
If you enjoy those then I recommend Lorenzo il Magnifico. Our group can't get enough of it. So, I just preordered the expansion. We've also had great success lately with Amerigo and Concordia.
