Sacred Haven of Debauchery

I remembered how my brother and a neighbor used to build a base for robots/soldiers out of building blocks when we were kids. The structure was a single-story building because many rooms were needed for different purposes. There were various storage rooms, bedrooms (with beds), and so on. I really liked it, and for some reason, I didn't do anything similar myself, maybe I just didn't have enough imagination at the time. I just came up with stories and played. So, I started thinking that maybe that's where my love for games with base building came from, whether it's some kind of XCOM or something survival-based and isometric.
