Interesting Solitaire Concept

[JLV]

I ran across something called Four Against Darkness a couple of days ago. I've only read reviews, and haven't ordered a copy yet or anything, but it sounds like an interesting concept for solitaire play.

Of course, it's designed for D&D-ish games, not hexagonal games, but the concept seems to be that you randomly generate rooms and passages based on both a system and the choices you as a player make, and then deal with the creatures therein (also randomly generated -- but done so within the story concept of the adventure you are participating in). Oh, and your party is apparently composed of four figures...

This seems like it might be an interesting concept for a new generation of "solo adventures" for TFT. However, having said that, I need to repeat that I haven't yet acquired a copy (and probably won't until my next paycheck), so in the meantime, has anyone else out there run across this game yet? And can you share anything about it from you personal experience?

It seems to have been a thing for a while since there are apparently a number of adventures as well as what appear to be two "core" rulebooks (Four Against Darkness, and Four Against the Abyss), though the latter appears to be more for higher "level" characters...
