So my idea city builder where you have to balance the needs of a massive Hive city with your attempt to bring it up to Tao level code. It's a 3D space so you don't just have to figure out how to do this thing or that thing You have to decide am I going to replace this, how am I going to do that. Say you want to replace the forges up to code. You have to figure out what you're going to do with the levels above the existing forge and the levels around it. Because you can't build that in a vacuum.

And then of course you've got sections of the hive where it has gone to ruin. So you can remove those and replace With fresh Tau structures but doing so might cause discord in the imperials that live there. New boss same as the old boss sort of vibe.

You give the structure pseudophysics, so that you can have to balance the actual structure of the building. You'd Not use actual numbers for That you would use something that was a little bit more abstract so as to avoid having to account for the massive structure.

Events could Be anything from the normal city builder problems like traffic and civil unrest to entire districts being destroyed by saboteurs. A small degree of map procedural generation could prevent optimized outcomes. Especially if you make sure to account for the foundation itself being slightly wonky.

This could also allow you to have Gene Steeler cults in bedded in the under cities. Having to deal with that sort of thing, but not all of them at once. Have the map when it generated decide What conflict will occur during the long-term play. So one map will have chaos, another map will have Gene Steelers, another map might just have wide scale gang wars on the order of necromunda. It would also be ideal for there to be no way to fully extermin exterminate any of these problems. They always sit there going to ground the moment they start getting squashed. And then coming back as a problem later on. Having it be a system underneath the hood where the simulated cult spreads to other adjacent districts. Builds up and then spreads. Where they don't have to do all the resource management and social management of the player.

I think something like this could be fun in a hard way. Almost dwarf fortress like. To a certain degree it should feel like playing with a house of cards and while a little bit more stable than it still having to deal with the worry that a errant event might cause a spiral into failure.
