In light of recent events, I think this is a great time to implement a sickness/disease type event in the game. This would teach the users playing the game how to handle real life situations with sickness. The overall gameplay idea is this: One of your colonists gets an unknown alien type virus. This leads to the rapid spread and death of many colonists, and you have a few options of how to deal with it. Some of the base options can be this: [Research a cure], [Quarantine everyone], [Do nothing]. These would all have their own individual consequences. I like this idea because of how broad this entire topic is. This is calling back to a post a while ago made by Wadaling along the lines of disaster events, and I believe that an implementation of some sort would be cool.
