Dwarf Fortress is a free game.  You can download it for free and play it on your computer.  Dwarf Fortress is a sandbox strategy game in the vein of the Sim City games, but is more open-ended.  It’s a game about creating a colony of dwarves, and guiding their development over many generations.  The objective is to explore the underground world, find things to mine, build things, and explore the natural environment.

Dwarf Fortress is an amazing and popular game where you control an entire dwarven town, and have to care for all of the dwarves that live there!  It’s a great game, but also really hard to learn, and it is definitely the kind of game that has a steep learning curve!  The cool thing is you can learn and make the game more fun by experimenting, so that’s why the game is hard to learn!  I think you would have fun with this game if you try it.
