Dungeon seed generator

21 November, 2008 at 11:18 pm (game mastering) (, , , , , )

I decided to create something that gives me ideas for dungeons, as, for me, having no creative limits means not getting anything done. Abulafia is the natural place for such creations. So, hereby I present the dungeon seed generator: http://random-generator.com/index.php?title=Dungeon_seed

It is supposed to generate enough information to build a small dungeon, or a possibly partial level of a megadungeon, around. To get a new set of seeds, refresh the page or click “article” just above the “Dungeon seed” text.

The generator is currently functional, though not as good as it should be. Particularly the layout seeds are weak. If anyone has good ideas to offer, post them here or modify the generator itself (it is a wiki, basic syntax can be used via copy-pasting). (I deserve the right to move particularly fantastic items of layout or otherwise to the wonders portion.)

I’d like to thank Phased weasel for suggesting that the lowest part of the generator only provide a single entry, not several.

As a bonus for any who have read this far, there is another generator that you might want to use if players characters leave a dungeon, especially for a longer period of time. (1 entry for an absence of a day, 2 entries for week, 3 for month.) The generator is a bit more boring than the (hopefully) evocative dungeon seed generator; it assumes a complete dungeon and makes it potentially more interesting to revisit. Also: It is not a substitute for the dungeon and residents thereof responding to adventurers, only an add-on. Link: http://random-generator.com/index.php?title=Dynamic_dungeon

Rules analysis

16 November, 2008 at 5:23 pm (rpg theory)

Significant amount of roleplaying uses rules, by which I mean mechanics in the context of this post. Specifically mechanics made explicit by a book or note paper or oral agreements. In this post I will attempt to outline the scope of analysis that only considers the mechanics.

I will not analytically define mechanics here. (Reason: I don’t have a good necessary and sufficient conditions for something being a mechanic.) Let it suffice to say that anything manipulating numbers or ritual phrases or dots is a mechanic. The description of a trait or feat is a mechanic. Terms like scene or encounter may or may not be mechanics, depending on their level of codification.

Formal games

A definition: A game is formal iff it has mechanics and if any event happening on the level of rules can be explained entirely by the rules.

The first condition is so that freeform, defined as being ruleless, does not count as formal.

The second condition means that if an observer can only see the rules-level exchange, that follower completely knows what is going on. Or: There is nothing outside the rules that can determine what will happen within the rules space.

I’ll call a game highly formal if it uses freeform or incompletely defined traits (e.g. my character is strong and so gets +3 to all rolls related to breaking things by brute force) and is otherwise formal. A game with such traits is not highly formal because the meaning of words in natural language is seldom exact and explicitly communicated.

Formal games exist: Chess. Highly formal games that are not formal exist: Universalis. Games that are neither formal nor highly formal exist: Freeform (and in the non-trivial case, say, Runequest). Hence, the definitions are meaningful.

The formality of roleplaying games

My claim is that there are very few games that are formal and roleplaying games. Highly formal roleplaying games are plentiful, though, and can be analysed in very similar way.

Almost all roleplaying games have a set of traits, player-defined or not, that have meaning according to the meaning of the relevant word in natural language. One possible exception I can name is called Rune. It is notable in that there is a strict by-the-point procedure for game master to use in constructing what amounts to dungeons; every trap, monster, and way out must be compensated for. It is precisely due to this extensive preparation that the game might succeed at being completely formal. All the qualifiers because it has been a while and I don’t remember if the game is actually completely formal.

My second claim was that highly formal games can be treated as formal without making significant errors. This is true because the ambiguity of highly formal games comes from the ambiguity of natural language. People who have played together for long, know each other, or are committed to certain source for their fiction (“this is a Star Wars game”) are likely to interpret the traits in similar way, or at least know the way in which the other players are likely to interpret the traits. Hence, the more the aforementioned factors are true, the close to formal the game is for that particular group. Treating a highly formal game as formal means simply going to the limit; it carries the assumption that the aforementioned conditions are sufficiently met.


Consider the set of rules of a particular game. Take a subset of this. The game this subset defines I hereby define a subsystem. (For more exact definition, consider that the structure of the rules-set or infastructure that supports it is not removed, only the rules directly defining player actions or consequences thereof are.)

Subsystems can be formal in much the same way as games can. For example, the character generation of several games is formal or highly formal. Combat systems may or may not be.


Any tool used for analysing formal games can be easily extended to the realm of (highly) formal roleplaying games, as well as select parts of other roleplaying games.

As an example let us consider game theory. For highly defined games one can simply assign utility to relevant mechanical outcomes and then consider the game as a standard one.

I’ve been somewhat busy due to university and visiting my parents for (now third) consecutive weekend. I make no promises, but more posts are possible in the near future.

1. Reynard’s blog on Enworld has material on sandbox play and random encounters. Of especial notice is this post. Unfortunately the RSS feed does not seem to be working.

2. Jonathan‘s rpg blog anthology project. If the project works, more people will be able to read the ramblings of random rpg bloggers. If it does not, J will hopefully still list the nominated blog posts or some best-of summary, so it will still be a way to find good posts. Contributing takes little time and gives you an excuse to re-read a few good posts, if you are so inclined.

The following are links to my own projects. So, not much to see, unless you are especially interested in my projects. Both the wikis have an RSS feed available. There is a page about wikis, including a link to Abulafia, which you should use.

3. Wiki of persistent fantasy rpg / In a Wicked Age clone / my default no-prep game.

4. Wiki of the dungeoncrawling rpg I have GM’d a few session of, and have been developing during my free time. Rules update is the most relevant page there. In the unlikely case of some reader wanting to contribute, ask via email, blog or the option in the wiki.
