Let Base Upgrades Visually Change The Den
It would be amazing if, as we upgraded the base, we actually got to see those changes reflected throughout The Den.
From what I’ve seen so far, most of the visual changes to the base seem to come from story progression and the characters you meet, as they begin occupying different areas around The Den. I really like that, but I think it would be even better if the upgrades we purchase also physically changed the base.
For example, if we upgrade the Medbay to add more beds, it would be great to actually see those beds through the window afterward. Even better, while an upgrade is being built, that part of the facility could temporarily look under construction—workers welding, droids carrying equipment, sparks flying, scaffolding going up, or the area being closed off for a Cycle.
It could also be really fun to have some light base decoration or customization. Nothing crazy, but enough that we could make The Den feel a little more like our company's home rather than simply a base we operate out of.
Seeing the base gradually become busier, better equipped, and more lived-in as Zero Company grows would make upgrading facilities feel much more impactful. It would give that feeling of starting with a rough mercenary hideout and slowly turning it into a proper headquarters over the course of the campaign.
