Long as it’s part of a 10k prestige settlement you get footfall, need 5k on the beacon itself for max footfall. Otherwise you probably won’t get anything. But if you build a nice, useful bridge and people actively use it may as well get paid. Lava bridges particularly.
Won’t catch me near lava, sorry. Building bridges so others can get to places is a nice idea, get enough experience so I can handle level 3 and 4 planets and go and build a bridge. Even on level 2 planets that seem to be mainly water so players can get around better.
