      This is beautiful! And must be even more beautiful from technology side.

      I have recently became interested into procedural generation as my free time hobby. As a backend software engineer I was looking for a side project with no commitment. Which would be flexible to apply different types of technologies, boring and interesting at the same time. "The Forever Project" [1] article describes motivation behind it.

      Since I had no experience with Rust, game development & procedural generated stuff, combining everything sounded pretty covering my "Forever Project" theme. I'm currently going through Rust Rougelike tutorial[2] to get basic understanding how games are being developed & maps are generated. I like the tutorial a lot because it covers so much different topics. From game dev, few libraries, to different approaches of maps generators.

      There is a lot of content there but I'm already raising questions to myself where to look next? What should I learn & focus so I could deepen my knowledge in procedural generated content? I understand I always can read random tutorials (what I'm doing) and try to glue something from them. But maybe you have advises or more guided content as books, long tutorials, courses?

      Thanks.

      Indeed. The Here Dragons Abound author's blog post on the overhead of maintaining this very cool open source project for the benefit of others [0] is rather eye opening. This is a blueprint for what it takes to do it correctly, often for very little reward.

      Also, apparently he is a contributor to Nethack.

      "Here Dragons Abound"[0] is another interesting take on this topic. The guy's been working for about a year now to beef up Martin O'Leary's work[1]. Fascinating read through if you start at the first post.

      Finding good fantasy mapping blogs is hard, I don't know too many, to anyone else interested in this Here Dragons Abound[0] is really good resource.

      Any others people really like?

      Inspirational stuff, with lots of great references to the OGs at the bottom, and source available. Now can it be merged with the look/feel of https://heredragonsabound.blogspot.com/. ;)
