Hey,
thanks for the update :-) Looking forward to the next release.
I was a little bit surprised when you wrote you bought DF. I played it years ago, and it was completely free. I checked it, classic version seems still to be free, Steam version costs but seems to have a completely reworked UI. Although the UI was a main problem in the classic version, I'm not sure whether it is worth the price. To be honest, I didn't stick long on this game, because I soon reached the point where my dwarfes lived in safety, and it got boring.
Currently I'm playing the old Neverwinter Nights mod "A dance with rogues". Maybe the best adult game I have ever played, and from what you wrote about your gaming preferences, you might like it (if you have no problems with a little bit outdated graphics). Primarily a challenging RPG with a dark story, spiced up with a lot of lewd scenes and a lot of beautiful clothing.
