As a serious game to save the world, why are my players not serious at all? I brought you in to let you farm, mine, build infrastructure, and improve technology, but you are always thinking about getting stuck Bug, just thinking about skipping class? Can’t grow crops in the cold weather? Then, if you think 'Put it down, I’m a serious game' is not bad, please don’t forget to recommend it to your friends in QQ groups and Weibo Oh!
