The Anarchic Kingdom: Release, Publicity and Lessons Learned

final-rankings-at-the-end-of-a-game-of-the-anarchic-kingdom

23 Jun: I released The Anarchic Kingdom on Saturday 22nd May. This was quite a bit of work, and required some preparation beforehand. Firstly I had to do some last minute development tweaks. The beta time limit was removed. I also developed a version that never quits, but simply restarts, which is necessary for the game to be played in an embedded web page where you don't want to see the DOS prompt. These were simple and relatively painless. Then ... (read more...)

The Anarchic Kingdom: Trying it Out

recruiting-new-forces-in-the-anarchic-kingdom

16 Jun: The DOS Spring Game Jam is pretty relaxed about timing. It's not a competitive jam, so participants are welcome to start development early, or even submit things that they have been working on for a while. I took advantage of this leniency by implementing The Anarchic Kingdom in the month before the jam, and then reserving the month of the jam for testing. This went mainly to plan. Some testing of the text mode version was done during ... (read more...)

The Anarchic Kingdom: Making it Pretty

starting-with-your-barony-in-anarchic-kingdom

9 Jun: The original Demesne was to run on a computer that had a screen of 640x240 pixels in 16 greyscales. I had conceived a graphical art style that put most of the action on a tapestry hung on a castle wall. Menus would have buttons styled after scrolls of parchment, and player selection was by choosing a coat of arms hung on the castle wall. The eventual target platform for The Anarchic Kingdom , an 8088 PC with 320x200 pixels ... (read more...)

The Anarchic Kingdom: a Simple Idea for a Game Jam

introduction-to-the-anarchic-kingdom

2 Jun: Last year I had hoped to develop a strategy game in a month, for the DOS Fall Game Jam 2020 . I chose a wargame project I'd implemented on the Psion, The World at Strife , thinking that reimplementing a game I'd already written wouldn't be too difficult a job. But I found in retrospect that it was hopelessly ambitious for a one-month game jam. That game is still in development and will eventually become Barren Planet. For ... (read more...)

The Anarchic Kingdom: from the Dev Diary

choosing-players-in-the-anarchic-kingdom

26 May: Now that The Anarchic Kingdom is out of the door, it's time to look back over the development process and share it with those who are interested. You'd think that such a simple game would have a short development life. But development of this game started in about 2006, on a different platform. Back then I was interested in developing for the Psion Series 5 , a once popular handheld computer that had become obsolete half a decade ... (read more...)

Building a Dungeon Level

a-sample-dungeon-generated-by-the-levelmap-library

28 Apr: I've been building a dungeon generator library for use in future projects, called LevelMap. A further development of the dungeon generator used in Ossuary , this library will give more variation in dungeon shape and construction than we see in Ossuary. Ossuary's dungeon creator works on grids at two levels. At its most detailed, it has a strict 16x16 tile dungeon. That space is split up into nine cells on a 3x3 grid. Each cell of 4x4 tiles ...

A Palette Selector

24 Apr: A recent thread on our Twitter account about CGA palettes resulted in a new graphic to show all the different 4-colour palettes available in the 320x200 graphics mode. It's an improvement on the simpler design I been using for the past six years, and shows what kind of dithering effects and background combinations each palette gives. I'll be using it to choose the best palette for each of my future games. It's presented here for you to save ... (read more...)

The Wargame Engine Behind Barren Planet

a-hypothetical-cwg-wargame-set-in-ancient-times

10 Apr: Barren Planet is based on two libraries. One is CGALIB, the graphics library used by my existing game, Ossuary . The other, CWG, provides the basic game rule mechanics behind Barren Planet and, hopefully, future games too. I want to talk about CWG in this post. CWG controls the battlefield. It defines the unit types that will be present in the battlefield, and the terrain types that will be present on the map. It holds the map itself, ... (read more...)

Ossuary Development Retrospective: a Post-mortem

playing-ossuary-as-a-mage

20 Feb: It's fair to say that the PC port of Ossuary hasn't been as successful in its early months as the Spectrum version was in 2013. The Spectrum version got a few videos in its first few months not solicited by me. So far one video has covered the PC version, but only after I made the content creator aware of the release. I did make some promotion efforts. Contrary to my previous practice, I discussed development on twitter ... (read more...)

Ossuary Development Retrospective: Testing and Release

the-ossuary-high-score-table

13 Feb: During development I was constantly playing the game myself. But there came a time to let other people try to break the game. I tend to prefer closed beta testing, where I know who is plaing the game and can keep in touch with them to get their impressions. I did advertise publicly though, as I knew few people willing to put time into testing an early DOS game. I set up the Discord server initially as a ... (read more...)

Ossuary Development Retrospective: the Coding

ossuary-assembly-language-code-for-the-zx-spectrum

6 Feb: The ZX Spectrum original was written in Z80 assembly language. That's the only way to fit a decent game into the memory of the 16Kb model. I'm not fluent in 8088 assembly language, but I am confident in C, so it made sense to use C as the development language. The 8088 is quick enough to write a turn-based game without resorting to assembly language. I started out using OpenWatcom C's own graphics library to draw the graphics. ... (read more...)

Ossuary: a Development Retrospective

starting-out-in-the-ossuary

30 Jan: With the launch of the DOS games web site I thought it was a good time to look back at the development process for Ossuary, my first full game for DOS since my early freeware/shareware attempts of the 1990s. Ossuary wasn't originally developed for the PC. It was one of a trio of games for the 16Kb ZX Spectrum, a somewhat more limited system than the early PC. I chose it as my first DOS project because I ... (read more...)
