>>14070148>the underground was betterAAHAHAHAHA.
The only purpose of the underground was to get rocks to trade for furniture. All the furniture went into the same shitty 16x16 room, and only had the value of grinding for plates.
Hiding a transferable, customizable base in a tree, bush, cave, etc. with dozens of preset layouts was the shit. And they let you challenge that base's trainer once a day, and the battles DID give experience points.
