The Gaming Center

look no further than dwarf fortress it's free to play and can be downloaded from the developer's website http://www.bay12games.com/dwarves/

I highly recommend getting the game from here instead https://dffd.bay12games.com/file.php?id=7622 as it comes with the base game and several improvements. One of those improvements changes the graphic from ASCII characters to actual textures. This really helps make the game come alive. It also comes with a few tools to help make managing your fortress much easier. Contrary to popular opinion dwarf fortress isn't hard to play it just has a lot to remember. As such, I recommend consulting the wiki as you play https://dwarffortresswiki.org/
