It’s slower than fortress mode but the cool thing is to interact with known entities that you encountered during your fort or you can use it to get a feeling of the world more closely and then make a fort on the area.

I think if dwarf fortress was just this mode you would prefer things like caves of qud which is more polished in that regard but you don’t get the fort interaction you have in dwarf fortress.

I mean the level of interaction is as deep and convoluted as you expect from a mode in dwarf fortress.
