Dwarf Fortress is a single-player fantasy game. You can control a dwarven outpost or an adventurer in a randomly generated, persistent world. The world is randomly generated with distinct civilizations spanning over 1000 years of detailed history, dozens of towns, hundreds of caves and regions with various wildlife. Command your dwarves as they search for wealth in the mountain. Play an adventurer and explore, quest for glory or seek vengeance. Extended ASCII character set rendered in 16 colors (including black) as well as 8 background colors (including black). Although Dwarf Fortress is still in a work in progress, many features have already been implemented. Please post all support issues in the forums for the game.
If you are a "casual" gamer stay away. For this game will scare you away very quickly. For those of you who enjoy a challenge and are even smart enough to install a skin pack if the ASCII is to much for you, you will not be disappointed. I'll go ahead and say that this is one of my favourite games I have ever played. The combat is amazing. The open-ended "sandboxyness" of it is astounding. It just requires a bit of patience and a lot of creativity. But once you understand it, this game is truly a masterpiece.

If you don't understand the game that means you are doing it wrong. I didn't understood it for the first few tries, but after I started to learn it for a few minutes (20-40) I was able to start to play with it with the help of the wiki.
But be warned if you are just a dirty casual this is definitely not for you, because this game is THE definition of gameplay itself. There is plenty of tutorials, tilesets and other stuff that helps you to understand Dwarf Fortress.
And why would you play it? Because of building and doing whatever you like, because of epic and awesome stories, because of brutal fights and weaponizing almost anything(like cats). Sure it doesn't looks good at first, but it will teach you what gaming is about. Gaming is not about graphics or casual wining, it's about having FUN, and this game has more of it than any other.
This game is absolutely awesome! The depth and complexity of the system are superbly completed by the randomness in the world creation and history. Can't wait to build bigger and better fortresses and explore their inevitable ruins, and then really start to get into the game!
