Dwarf Fortress's Adventure mode - a procedurally generated campaign that lets you approach the famously dense colony sim like a more traditional roguelite - is now out as a free update on Steam.
The game represents perhaps the most cavernous, yawping blind spot in my entire pile of shame. I do own it, but I'm yet to play.
I've already read a great deal of extended wordery on its merits - please, sell it to me in the comments in seven words or less.
Here's a trailer: Graham most definitely has played it though, calling its older incarnation "a good way to experience the charms of its procedural world and high level of simulation".
Personal anecdotes and experience are great and all, but what I really want is some deeply impersonal bullet-pointed features from a store page.
