First, I am a huge fan of these sandbox type games. I LOVE to explore, mine, farm, and build. I didn't know much about this game, but a friend showed me and now I'm simply addicted. It really is a great game base, with a very relaxing environment.
Second, I want to touch on the base building. Now, while I have not touched the later game content (so this may exist), I find it somewhat disappointing that I cannot build my own station (walls, floors, et.). I feel this could be vastly improved upon so that players feel a sense of customizability, unique to their play through, and safety. Players could store supplies inside (I like to have storage for EACH resource), have beds, and more. I really can't state that I have any hard ideas on this subject as I don't know anything about the system used to run it, or what you guys use to make you models for the structures, but I feel that this sense of customizability will greatly increase the player base, as people like to be unique.
Its all just thoughts on my part. I'm not sure if you guys are going to implement any survival requirements, but please don't. The world needs less harsh survival online pvp games. I moss my single player and co-op, and this is perfect so far in indulging that need. Thanks Devs!
