The invention provides for balancing a computer game, in which players can choose between different options for a plurality of actors within the game. The actors are described by parameter vectors defining characteristics of each actor. The cost of each actor is calculated, wherein the cost of an actor characterizes the amount of resources needed to obtain the actor. Also, the rank of each actor is defined, wherein the rank of an actor characterizes a usefulness or a value of the actor. The parameters of the actors are modified until the rank and the cost of the actors are proportional for each actor, wherein the constant of proportionality is the same for all actors. Thus, the various options become approximately equally successful and the computer game is balanced.
