Dwarf Fortress

Dwarf Fortress is a game from Bay12 that plays like an older 8 bit game such as The Legend of Zelda, but more like an 8 bit version of castle defense or Harvest Moon.

It is a survival game where you play as a group of dwarves trying to create a new home in a distant land. You must survive against thirst, starvation, plague, siege, and many other things that will try to kill you.

It is a fantastic little game that will suck you in and not let go anytime soon.

I really believe this would make an awesome addition to Portable Apps.

Thanks!
