Machi Kori, Castles of Mad King Ludvig, and Istanbul.
My quick takes:
Machi Kori - cute, fun little dice game. Probably much better once the expansions come out.
Castles of Mad King Ludvig - Like seeing the castles sprawl, but the game ends WAY too soon to ever get a really crazy looking castle. I think it needs to be twice as long.
Istanbul - the "starter" layout of the marketplace tiles negates the need for pick up some of the boosts, which takes away part of the strategy. Might be really great with the "hard" layout and 5 people (we played with 3).
