Prison Architect

Prison Architect is an indie game based around construction and management simulation where the player takes control of the running and building of a maximum security prison.

In-Yogiverse
Sjin currently has four seasons of Prison Architect videos on his YogscastSjin channel, although in his Rezzed Vlog he confirmed there would be more of it coming soon. Sips also did a gameplay of Prison Architect.

Story
Sjin has named most of the staff he has hired in the prisons he has been running, and they are often consistent throughout each season.
 * Pierre: The cook that somehow always wants a job in Sjin's prisons despite numerous riots!
 * Charles: The warden that likes wooden floor in his office.
 * Wally Workers: The group of workers that build Sjin's prison.
