Last weekend I got to play a couple of games of "Die Fugger", a new game from AdlungSpiele. It's a very nice little market game that plays quickly and requires some interesting decisions. The basic idea is players play cards in sequence, and when the 5th of a particular commodity is played, the round ends. At this point, the top three commodities are raised in price and the remaining two are lowered. The price wheel is circular, and when a commodity becomes too highly priced, it crashes back to the low values. There are naturally other details, but that's the basic idea.
It's fun. It also suceeds at something that is fairly rare: it is a quick game that doesn't feel really light. There are a ton of games out there that play in under half an hour, but most of them feel very light. I'm not saying that Die Fugger is as meaty as something like PrincesOfFlorence or PuertoRico, but it packs a good amount into a short game. There's not a huge amount of strategy, but some strong tactical decisions and overall good tension.
