One of the first things I have noticed upon building is that everyone can see the insides of your base, knowing exactly how to get to your loot. This is not only annoying, but makes it harder to keep your precious items safe. Also, there should be more traps and defenses. The only way to keep someone out is by spamming walls and doors, which is boring and not fun to make, or raid. With that being said I really enjoy the building system, and believe it's refreshing from the usual systems in other survival games.
