Isnt new for anyone that people use web maps during play DayZ. Its also know that the DayZ is a immersive game. So think on the i thought on an new map system that isnt the most real thing but would make the game much better avoiding people to keep changing between game and a web map (or a phone app).
1) Everyone should start with a map. I know that isn’t much realistic, but who didnt find your self respawn and try to discover where are you. I dont mean that a the player position should be displayed on map but the player should have a map in game since begin so this way the player would track where he is.
2) The map should be account wide (on item 3 it will make more sense)
3) During the player exploration the map will be updated showing the location of buildings, like the web maps. This will make people even more interested on exploring and the map would work as a achivement. So if the player visit a police station it will appear on his map, etc.
4) Areas where the player has already visit would already appear on map even after the player dies and respawn. This is important or other wise people probably won’t use the new map system too, because the current problem would continue (people get in game and then go to a web site map to look there he can find some type of building). Persisting the map already explored by the player will make people migrate from web site maps (or mobile dayz map apps) to the game inside map.
I know that this system isnt the more realistic one, but people changing between the game and a web site with a map isnt too.
