My ideas are small additions, but I think we could use:
- Raft drift
- Beds
- More fish (salmon, tuna, halibut, etc.)
- multiplayer????
That last one would just be kinda fun and isn't really an hard-set suggestion.
[Edit]
- I think scrap spawns too fast for how little I use it
- I think we could use more types of veggies and fruit
- Boats???
