Purify is a Simulation Game (SLG) which is focusing on
operation rather than collection. It caters some people's hobby
of operating equipment. It has richer form than the content.
In this game, the most advanced equipments are not always
the best. For example, when the natural temperature is suitable,
the player does not need to turn on the AC. To make the
BEST COLLABORATION, player has to choose the lower level
equipment. I design this term to remind people that do not
waste energy in our real life.
