Theme Prison 2000
A really addictive game that feels like it will never end. The title might be a little misleading, as I found myself worring about management a lot more than about architecture, especially since the player can't even build a multiple floored building and that he doesn't have to worry about the mathematical complexities that come with it. Despite the title, the amount of time you can spent with it is amazing. It has lots of mods and downloadable maps, a short but great campaign that functions as an excellent tutorial, an escape mode and it provides a lot of player agency in running the facility. It's simple enough for casual play, deep enough for the more dedicated players. I found myself going between playstyles, where I left the game open while I ran a video or podcast next to it.
However, the bigger your prison gets, the slower your system will run it. I've a 3,3 Ghz CPU and by the time I almost had a thousand inmates, the game ran definitively slower than before (though it was perfectly playable). The game also suffers from numorous glitches. Some experienced some severe bugs where parts of the area was unusable because the game said a building is standing there eventhough it was clear grounds. I noticed that workers don't reliably lay down powercables, where parts of it are missing by the end of the contruction. I saw the same issue with some maps I downloaded from the workshop, meaning that other players must have experienced the same. There are also a lot of glitches involving the behaviour of your employees, which often get fixed with a quick restart or reload of the game. Luckily, the devs continue to update the game with fixes.
I got this game for 5,60 euros, which (looking back) was a steal.
