Although it bears the name "manhattan project" it bears very little resemblence to the original. Energy Empires is a way better game. It's a worker placement + resource management kind of thing, with a "points salad" at the end. Those that like "Castles of Burgundy" and similar build-your-own-solution kind of thing will love this. It plays up to 5 which is a bonus. So far I've played it only half a dozen times but it has not "plateaued" yet.
