we played our first game of "The Manhattan Project" yesterday with 3 players and had China, Soviet Union and Britain in play.
We had the impression that "Britain" is very strong (requiring one worker of any type for getting 2 fighters OR "Remove 1 damage from 1 of your buildings".
It probably depends on the buildings in play, but in our game the "getting 2 fighters" (approx. on every third turn) posed a great threat of an air strike to the other players and even more defended very well against possible air strikes from the opponents; the OR-ability was never used, but demotivates the opponents additionally to air strike the Britain player.
"Japan" seems to be similiar, but requires 2 workers of any type to get activated.
Has anyone more playing experience to judge if the Nation cards are well balanced or that Britain and/or Japan are not overpowered?
