The 4 friends game needs all of them having purchased the game
It's really a pity that all the players needs to have purchased the game to be able to play at 4 players. Very often I want to play it and show the game to other friends but we are 4 and we have to play to another game instead, like Risk. Apart from not being very amiable with the costumers who bought the game, I am convinced that this is a very bad commercial policy.
I agree that the suns aren't as good as the old scrolls.
