Something I see a lot is complaints about bases being torn down because a player logged off for a few weeks. As most of us know, the decay system will remove your base if you don’t return for a certain period of time. However, someone completely new to the game will probably not be aware of this system, especially if they’re new to the survival genre as a whole. As far as I know, there is nothing in the game that directly warns you about building decay. There is no incentive to make a repair hammer either–there’s no journey step for it. Someone might read the description and think to make one to repair their structures, of course, but the repair hammer’s description only hints at buildings taking damage. Someone could easily misunderstand and think they only need to make repairs, not actively be present before a timer expires.
My suggestion is to put something in place to warn new players about decay. Perhaps make an early journey step dedicated to making a repair hammer, and put a description in that step that warns about decay in very literal terms, not just canonical story telling. That way a player will be aware of the system without breaking the game immersion too much. I think this is a reasonable idea based on another item–the Keystone. Its in-game description has a very bold, literal warning about the usage of this item: "WARNING: REMOVING THE BRACELET WILL END THE GAME AND DELETE YOUR CHARACTER " which is necessary because it’s a very crucial move to use it. Perhaps the repair hammer can also have a similar note in its description.
I don’t necessarily think the decay system needs to be improved, I just think it needs more visibility. Thank you for your time.
