I think that the current Juice Galaxy's proc gen open world and emphasis on exploration may lend itself nicely to some rudimentary sandbox/basebuilding mechanics. It would be really cool to carve out a piece of it to call home. Maybe I could even make a storage room to display all the wacky shit I find, or a garage for the juice car.
Some really simple mechanics may have a huge impact on gameplay variety. Imagine if you had to complete a side-quest to rent a house (or even one of the new structures) and then you get to do whatever you want with that plot of land. What are your thoughts about that?
