player should be able to gift coins to another player
Coins can't be gifted. Did you mean Gold?
Declaration should be one of them, a player should be able to set how many turns after the declaration should they be in war. Also, it should be set up so that no player may attack another without declaration
These are contradictive, but I know how this would be possible.
What do you mean by 'different maps that show different aspects of the world'?
