I was dissapointed by Prison Architect. I think it was a waste of €20.

I played 2 games with it. There were some bugs, but they were small. Gameplay is solid. However, the guard AI is horrible! My guards would move the prisoners to the dining hall(not sure on the exact name) and left them there to eat. On the way back, they would abandon a prisoner before they reached their cell, causing the prisoner to escape! Of course, Donut-diet Joe couldn't keep up with the prisoner.

I restarted to see if this was just a bug with the save. Same thing happened after around an hour of playing, so I gave up on Prison Architect.
