Drainage and Slopes

[Zumbo Prime]

I'm sure you've all noticed by now that it can rain quite a bit in-game. But in terms of practicality, where does all that rain go? Surely it can't just all evaporate or get absorbed into the stone! Like in the real world, that rain has to go some place. In theory, there would also be at least some kind of gradient on the ground and mountains as well. Together, this would cause the rain to go someplace.

For instance, if the player excavated a mountain, the water could flow into the excavated areas if the grading wasn't altered or pumps weren't set up. Or the player could excavate certain areas to create ponds or ditches to direct the water somewhere, e.g. to create arable land from sand. If there was a huge rainstorm, low-lying rooms and outdoor areas could flood for a time which would have to be remedied for farming areas. After all, before you can have a town or productive land, you need proper drainage.

I like your idea. The game also needs more impact from the rain!

Only thinking with idea of
* Floods -
Crops destruction or loss due to heavy rain.
Rivers increasing size during heavy rain.
Illness coming from floods.
Loss to items exposed to this heavy rain.

It would be a cool first step to make rain moisturize the ground. If a tile reaches 100% moist.. moist.. moisturity(?) there could be an overlay "water" same as from snow with similar effects. Only difference would be that at 100% water, passing would be prohibited.

Then you need a new ammo type "sponge" for Mortars, and shoot the moisture grounds dry again.

I really like this idea! It would allow people to actually farm properly in Extreme Deserts, and it'd also make the game a lot more realistic!
