Agreed - will it be for gaming, or more of an impressive backdrop?
It started as a pretty bit for a demo game.
After having played some boardgames I had an idea whereby I could come up with some rules which would see bases of figures contesting spaces within the city. These spaces might include open areas but mostly would be blocks of buildings. Certain building might have special effects, so a temple might have fanatical defenders and impact morale nearby if captured, victorious troops capturing a bar might be 'delayed' for a couple of turns. Uncontested routes might allow swifter movement. It would use kind of boardgamey rules for playability, with the figures as pretty counters.
I needed a reasonable area to do this, hence the extensions, and wanted the ability to change the configuration inside so it didn't get dull. Nearly done with the modelling and I'll show how I've set it up to allow changes to be made internally. Whether I ever get round to the rules - who knows. I had hopes of making it bigger and adding a harbour - I have started scratchbuilding some ships - but health is a bit iffy so that might be curtailed in the face of a host of other partially completed projects.
Thanks for the comments - more soon to interest you I hope.
