What does /rocks/ think of rock representation in videogames?

Minecraft has it poorly done
>diorite and andesite are common in spite of lack of stratovolcanoes or high viscosity magma
>a few clay blocks aside, sea floor is line with dirt instead of silt
>no shales beneath the ocean silt
>no pillow lavas beneath the shale
>no gabbro beneath the pillow lavas
>no metamorphic rocks such as schist or granitic gneiss and no cratons in the continental interiors. Felsic rocks such as granite and diorite are often found under sea floors.
>no turbidites
>Diorite is found buried at great depths with no signs of metamorphism
>coal is found buried in normal "stone," implying it must be sedimentary, yet low viscosity magma also freezes into this "stone" implying it's igneous
>no basaltic dikes or sills in spite of frequent magmatic activity in the crust
>magma pools are not associated with plate boundaries or hotspots
>no plate boundaries, no orogenic mobile belts
>no patterns of folding or strata distortion in the mountains
>no apparent mechanism for mountain uplift
>aside from sand and sandstone deposits, no signs of ongoing sedimentation
>since granitic and dioritic plutons spawn randomly, there is no real explanation as to why sand is only deposited in certain spots, often NOT downhill from a large granite or diorite deposite
>rivers in mesa biomes don't flow from a coherent source
>no apparent source of sediments for deposited in mesas, nor is there implication that the sedimentary massif was uplifted to a higher elevation than the sediment's force via plate tectonics
>deserts are found surrounded by warms seas with no mountains to produce a rain shadow and no alignment to westerly winds. Complete lack of atmospheric Hadley cells
>diamonds are not associated with kimberlite pipes
>volcanoes do not produce ash or gases
>no alluvial fans at river mouths
>granitic plutons not associated with coherent intrusions or mountain building episodes
>year-round snow capped mountains don't have actual glaciers or signs of glacial activity (moraines, u-shaped, valleys etc)
>metal deposits not formed in veins or with evidence of hydrothermal fluids

What do you think of Dwarf Fortress then?

It could be improved but generally reasonably good as far as video games are concerned.
Generally magma/lava is totally unrealstic in games. There is no magma sea like in dwarf fortress for example.

You might wanna try the terrafirmacraft modification.
It tries to add realistic sediments and many rock types which are only found in certain spots.

dwarf fortress just takes a ridiculous amount of minerals and rocks and puts them in horizontal layers on your map. I think it does not mix up sediments and igneous rocks etc, which is pretty good. The names of ores respond to their rl-counterparts (malachite is gonna get you copper etc.), even though the quantities of metal you get out of them is way out of proportion.
Anybody who ever looked at a geological map knows that the horizontal-layer approach can inherently not lead to anything even remotely realistic (or interesting, for that matter…).
Not much to do with rocks, but a pedologic rehaul would also help a lot
