My wife is a water resources engineer, a type of civil engineering focused on flood prevention and erosion. I think I've finally found a PC game she's going to be excited by.

Other games you might want to recommend, as they include good fluid simulations: From Dust and Cities: Skylines (although not a huge part of the game).

Oh she is well aware of Cities: Skylines.

I'm an accountant. I really /really/ want to play an accounting game.

(I'm not an accountant, although I have partially trained as one)

I like poking around with these sorts of sandboxes, but in order to gamify it, you might need some objectives, limitations and planning goals, eg: - you have a limited amount of some mineral or rock that erodes quicker or slower than others, and you need to move water from one location to another. - there is a magma chamber growing under a mountain. Move the villagers out of harms way / destroy enemies. - introduce s…

Plenty of us prefer open ended sandboxes/simulators like Minecraft, C:S, flight sims. Following game designer gets boring fast, setting own goals is always fun Speaking of CS, I wish this simulator had heightmap export.

Minecraft has a story and an ending, with the opportunity to get there as you'd like. Why not have this for this game?

May I introduce you to spreadsheets in space: https://www.eveonline.com/

It's got big corps and large money management, etc. You can scratch that itch for sure.

I've myself tried to create a small simulation of water and erosion, and although very fun I found it extremely hard to implement. (so well done to you!)

Is it a grid based system underneath? How do you calculate water displacement, is it with a vector field? anything else you'd like to share about the implementation?

Populous was a game (series of games) where you could raise and lower mountains for various reasons, this mechanism could be used in a game like that. Actually I do remember a game in a series like that - may have been a sequel to Black & White? That had things like (water) erosion and the like as well.

I'm bad at managing my own money, I'm wondering though if a game that sneakily teaches budgeting etc might be good, maybe call it 'the American dream' and it's basically the Sims but with real expectations on how life will play out with random tragedies etc.... car breaks down. it could even include wages from statistical sites and mortgages and rent pegged to the national average, as well as healthcare.

I was just watching this video last week about the Voxel Space technique used in the 1992 Comanche game by Novalogic.

The video mentioned that besides the rendering engine, Novalogic also develop their own terrain generation tool, with erosion methods, elevation decay, etc.
