- Patrons voted for gallery room which was released as 1.1 on february 17th 2019 (so no new content)
The way you presented both of the above makes it seem like no (little?) effect (by the developer) is needed to implement such a feature, like all they needed to do was click a button and "hey presto" there was now an instant galley.1.1 was a just a gallery, so no content.
Often retro fitting a galley into an existing game, that wasn't designed from the start to have one, requires either:
A. Restructuring/refactoring the code for the events that will appear in it, which then leads to needing to retest the entirety of the standard play-through to make sure it still works as expected.
B. Cloning the existing events to make "galley only" variations of them.
