I am an experienced computer programmer, but don’t have much experience with modding in general (or modding No Man’s Sky in particular) . What I would like to do is to create a mod so that there are 100’s of alien races instead of just the 3 that I have actually encountered while playing NMS. Is this possible with modding, or are you limited to just changing things that already exist (e.g. making creatures larger)? Does anyone have suggestions as to how I would get started?
