Because ore scales, it becomes increasingly difficult to move away from spawn, though if you landfill you can get super rich deposits... it'd be nice to flatten the amount/resource * richness setting. Separate settings for item resources vs fluids would also be convenient.

On the other hand it becomes increasingly difficult to obtain enough ore in late game because one is constantly moving miners. Lakes offer some method to work around this as well as a stone sink.

Though I do think that ore values ought to be retweaked so early ore lasts slightly longer and later ores don't last quite as long. This would help keep the pressure on available building space even when the base has reached 100 spm stage.

Gotcha. I'm playing a mod where there's more intent to keep moving. Seeing >10 gigaore on the map for one resource with normal richness is a bit disheartening (especially with ore is lava is on).

How does landfill increase deposit richness? It creates land with no ore on it.

Landfill over an ocean -> no lava burn or building restriction -> reach farther ore patches. This is a very old thread, friend \:p
