What if "loot chests" spawned rarely that could only be unlocked after walking a certain amount of Km/miles? They could also be Available at the shop for only a few unobtaioum or as low as 99¢. It would provide s cheap way to maybe get unobtaioum and it would encourage folks walking and not just claiming land and leveling if up... This is just a loose idea so some critique would be awesome
This is also another valid theory!
I will adjust the way resources are picked up in the next version and add a notification when your base's inventory is full (preventing collection in such cases, instead of the resource simply disappearing).
It was level 1 so it takes the same time to just capture it from the base even sitting at home. So it still doesn't stimulate walking. Maybe that tactics is more helpful for well-defended lands as guard tower doesn't spend armies.
