Hey we are part of the Steam Sale for the online Roguelike Celebration festival that celebrates roguelikes and procedural content in all it's forms.
I am also a speaker at Roguelike Celebration talking about how we generate the world, story and characters in the game. If you're interested in how these types of games are made you should check out the full schedule. It's a very well organized event run by some lovely people.
Safe winds - Captain Alex
