The Manhattan Project is a very fun and solid game. The thematic is well glued to this worker placement and one seems to be really racing for the bomb! Must say that it works well with 2 or 3 players but it really fits a 4 and 5 player game.
bombing, espionage, factory building, "yellow caking" and more much more...
One of my 2012 favorites and can´t wait for the expansion to be released until the end of this year, that´s why I backed it up on Kickstarter!
