A lot of people compared Rimworld to Prison Architect I guess for similar graphical styles. I found Rimworld before PA, have held off because money's tight, but ... well ... its on a 75% off sale on Steam midweek madness sale right now for as low as $7.42

*GRAB!*
You can even pick up several extra titles bundled in for ten bucks total at the "Prison Architect Introversioner." Good deal!
Had it pirated it a couple days ago and actually rather enjoyed it. This sale came at the right time hah. Thanks for the heads up.
its a very good game! buy it, you dont regret
Oooh I can recommend
the prison escape mode was pretty neat lil fun aswell (although kinda barebones when I last tried it)
