Not that it's close to done yet.

It has proper graphics (though simple, it is a one man project). It includes utilities like Dwarf Therapist. The random events are not so random, but tries for better story telling.

There are some limitations, which might or might not be fixed. For example, there is no digging down, only one z layer, so you cannot build elaborate fatal traps.

Overall, I really like it. :)

I haven't tried other DF inspired games from Steam, though...

Subversion tried to generate everything and have deeply complex simulations -- mostly because he realized Introversion couldn't design every last detail by hand at the scale the project was trying to provide. PA itself was actually directly the result of Chris realizing that he had more fun trying to build these intricate simulated scenarios than actually playing them.

There's a beautiful demonstration of Subversion where he shows a heist scenario with intricate alarm and security systems and how the player could just bypass all of it by simply shooting people -- that was apparently the dying blow to the project.
