It has finally come to this: after several years (turns) of planning, you gather all your soldiers into the largest army you have ever assembled, leaving regions of your empire unprotected while you march to conquer Rome.   But Rome will not go without a fight. As soon as you lay siege to the city, several Roman armies rally to defend their city. Their armies combined are twice the size of your own army and the computer tells you your chances of winning are 1:3.
