The Unreal World is a game i would want to see on the frontpage someday. It's a graphical roguelike set in medieval finland/scandinavia and the goal is to not die. You go around fishing, hunting, setting traps, building some shelter to sleep in or even a house if you have the patience and do a little bit of everything, it's awesome.
To me it is what adventure mode should be in DF and with constant development(slow but steady development that is) it really has the potential to get better than it already is.
The game is incredibly hard in the beginning(for me at least) when it is hard to survive even 2 weeks but later you will most likely be able to get enough food to last a year.
It is definately worth the few dollars it costs.
