Cold City is a very cool game. It has the characters playing members of a multinational group in 1950 Berlin, tasked with hunting down remnant monsters created by the Nazis.
The setting is neat, with lots of good information about the state of Berlin at the time. The monsters in the book were perhaps a little uninspired, but that is easily sorted out by re-reading some Hellboy or Tim Powers' Declare. This might also be simply a matter of taste.
The system seems like a solid conflict resolution system. One nice touch is that yoiur traits must be neutrally worded and can be positive or negative, switching due to fallout from conflicts (for example). There's also a system to measure trust between the players, pretty much a second generation of the trust mechanics in The Mountain Witch.
Character generation is really good - I particularly like that you have to choose your stereotyping of the other nationalities as part of it. Each character also has a national and personal secret agenda, a convert goal that pretty much defines an endgame for them if they achieve it.
