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.
