Just a small suggestion. What if in hard mode or something as well as having to get a map you had to actually get to the locations before the node would show up on your map.
This would be most effective with maps that are as large as possible, encouraging the sense of adventure. Think the Fallout series, where you can see a map of all the playable area from the beginning but can only see the location markers and fast travel once you have actually been to the location in question (the only exception from this is when you get directions from an NPC, but you can only see the marker but not fast travel). (Just to clarify, I am not suggesting to add fast travel to Unturned II, the travelling around is one of my favourite bits of U3).
Anyway, that’s just a little feature that more hardcore players might enjoy. Tell me what you think.
