There needs to be a way to have renewable resources so that you never run out and can always keep playing. At this point in time, there is a possibility that you run out of a specific resource and are unable to craft with it any longer.
Also, an end-game storage link would be cool for people who never go to their base. Then you could link your inventory to storage containers in your base to automatically transfer a certain resource.
I would like it if there was a free mode where you did not have to collect resources. That way, more creative builders could use their skills trying to make the most beautiful or functional base ever without the need for gathering resources.
