Dwarfs is a single-player casual game in which you guide your Dwarfs to mine the caves around your home base, find the gold, minerals and treasure - and try and keep them out of trouble! Dwarfs just tend to keep digging, following only their lust for more gold. So they will dig into water and lava, threatening your home. If that wasn't enough, they keep finding all sorts of nasty little monsters that have to be dealt with too. The player can build walls, dynamite holes in the floor, or turn earth to stone in an effort to prevent disaster. But in the end, success or failure will depend on the player's skill at directing his ever-growing army of dwarfs! And if the basic modes aren't enough, there is a complete sandbox, where you can create your own challenges - and a "Defend the Town Hall" mode where clearing out waves of enemies becomes the biggest challenge.http://www.dwarfs-game.com/
It seems as if Dwarf Fortress has inspired an Xbox arcade developer to create something quite similar, albeit much more casual and suited to people that like arcade style games. http://www.youtube.com/watch?v=TqU6-nlDOFY
The similarities are striking.
