More NPC characters
From the source on the Internet I remember hearing that there was going to be deer people in space engineers. I thought why not make NPC dear people that can do trade with you. Why not make them have their own suits as well as their own stations. Maybe have some of them be warriors and have others be peaceful. Have them ride around on ships and random counters. Heck even have them wear space suits this time with the helmet on for them. You could probably also make it so that they can explore as well.
