As a veteran No Man's Sky and ARK player and after spending several hours in Grounded, these are some suggestions that I think would improve playability:
- Add the ability to increase inventory space over time, and on that same note: add armor and weapon slots to the character tab so that these items aren't taking up general inventory space.
- Add dynamic weather, ie: rainstorms, snow, fog, etc. The consistently warm, sunny days get a little monotonous.
- Add some sort of character leveling so that players can increase damage delt to NPCs and damage reduction for the player.
- Add the ability to prevent plants from regrowing within base boundaries.
