We developed the game rules of Asterobots for JC2012 integrating “Catan” and “Galcon” to satisfy SG1. Interesting and SG2. Understandable. In “Catan”, the player earns points by gathering the resources and developing the land to win. In “Galcon”, the player occupies enemies’ planets, which pro- duce soldiers, with soldiers to win. In Asterobots, the player also occupies enemies’ veins with robots to win. The veins produce materials similar to “Catan” and robots similar to “Galcon”. Although the soldier productivity of each planet is constant in “Galcon”, the material and soldier productivities of each vein can be upgraded by consuming materials similarly to “Catan” in Asterobots. Although “Catan” has four resources, Asterobots has three materials to make game rules simple in terms of SG2. Understandable.
