Reputation ranks
Ranks only ever go up; points can drop but your rank stays.
About reputation ranksI loved exploring all the buildings, fighting my way into the wasteland. I liked the horde system, it encourages players to build a base and equip themselves, or you can just fly your way out of it with a plane, both options are perfect. What I did not like is that the mobs get tougher as time goes on. I understand that progressive difficulty is a very common thing in video games but I think there might be better ways to make getting stronger worth it.
