Mysteries of the Meandering Metropolis in the Hexcrawl Royale

The thing live about gaming most is setting design. My rule mods are a way of shaping games for my settings. My tables are portraits of my landscapes. So the mobile city thing which I started has more submissions.

A sample hexcrawl royale setting for all of walking cities and kaiju
Im envisaging a setting where most of world is wasteland with wild animals and monsters. Some primitive survivors live in the  wastes. Others hide in the dungeons and caves while the surface was purged. Then there are the great mobile cities remnants of wars between gods that wrecked the world. These cities battle each other and gigantic monsters.

Players could even represent a city if name level or party could be defenders of city or even rulers. A city or kaiju should die every session or a dungeon destroyed. Wiping out last representatives of a race or finishing off a god possible too.

While seeking resources for cities and dungeons to explore the city lords keep an eye out for kaiju or other cities. A defeated kaiju could be turned into a colony with a building and control device added. Looting a city would help to improve your cities stats but if you lose then you might need to resume life on a new city or take over from within of find a new home. You could also trade if city non hostile or related to your own or both too wary to engage. Some large powerful cities could enthrall smaller ones and run them ahead or use to scout or act as guards or decoys. When cities clash they colide and the populace take arms like ship crew and board each other looting, killing and enslaving.

Citadel Track Sheets for campagn
I could envisage keeping track of campaign area with hex map to record. It could double as a simple wargame and record any local kaiju, cities, ruins or dungeons or resources

City or Kaiju Stats d6
Strength - roll under score to inflict a hit
Defense - roll under score to resist a hit
Sight - range in hexes can see and chance with d6 roll of detecting
Visibility - range in hexes can be detected from
Move - how many hexes per day can move
Size - population capacity and volume (in hectares?)

STR/DEF related for combat
SIG/VIS can also be used for communications range
MOV/SIZ how fast how big

Invulnerable foes battle then get bored and wander off if they fight each other
You can attack any stat and victim gets to make a defence roll to resist losing 1 point
Cities in same hex always see each other
Stat up kaiju same way

d12 City Quest

Once a kaiju or city on map the DM tracks them till it leaves local hexcrawl map. They may detect each other and will usualy close. Most Kaiju start with a melee attack only using ranged if city does first or have already battled. They might use ranged on a faster or fleeing foe.

You could wander about some off the shelf setting and destroy it for fun like Krynn or Greyhawk or Mystara and stomp everything you dislike. Let local villains make or find a mobbile city. Lead your city on missions from the gods. Each player over a camppagn of a new city a week game. Eventualy each player develops bond to a favorite city. Players unite for a battle each with a mobile city and do some millennial event on a setting. A flying or spacefaring or plane shifting city could be nifty campaign

Such a game could be short or long but controlling a mobile city sounds like a high level adventure which I need more of.

Or use one of these classic hex crawls

or try Carcosa or Red and pleasant land or Mars or Dark Sun or Psychon


  1. You might want to also check out Chrome Shelled Regios, since it has a similar idea. Some of the side plots are complex, but the mock battles between mobile cities (when they aren't defending themselves against "Filth Monsters") over resources is quite mineable for ideas.
    I'd also recommend the Predator Cities tetralogy by Philip Reeve.

  2. A staggerig citadel probably needs air support and luckily eough in a fantasy world there can be a host of options: ornithopters,elemental zepplins, rocs, and griffon riders.
