I really don't remember the majority of the community complaining about the prison. Unless I missed a post somewhere it was kind of just changed to be changed. This prison looks nice, its just really not fun to fight. With the old prison it felt like I could just get on, fight it by myself if i liked or with friends just for a quick little fun event. But now its just tower defense and it feels like its lost its "entry level civ event" feeling.
And like I sad above, the prison you made looks aesthetically pleasing and you did a great job. I personally just enjoy being able to fight the old prison whenever as well as the combat it offers.
And this genuinely isn't me trying to continue the Asylum cycle of adding something, then wanting it reverted. The only people who ever complained about fighting the prison were cops who literally just didn't know how to fight it (cadets, constables, etc).
