New ores for immersion and a more 'engineering' feeling
So something that has bugged me with SE for such a long time is that it's got such a small selection of ores, so it's easy to get tons and tons of the basic ores currently and do anything. It would probably be easy if you only added 1-2 new ores and went from that, but if you add for example, the below ores. you enhance the survival experience, the game has more of an engineering feeling to it,
Coal - burn in blast furnace to smelt iron/other ores. possibly use as another power source on earth planet, can be found in mountains underground OR you can get a drop item from trees from the earth planet when placed in the blast furnace it provides a fuel source to smelt ores, once used up they become charcoal.
(side note: could add a diamond 'ore' inside the coal in very small amounts, and diamond refines very poorly so you need a good bit of it to create enough refined diamond, and you use the refined diamonds to create a diamond drill bit component which is used to create the larger drills.)
Copper - Used in components/blocks, copper can make wire components to add to blocks if computer components are needed.
Aluminum - Used in light armor, is a mixture of aluminum and copper/magnesium/silicon
Titanium - Used in heavy armor blocks, titanium plate instead of steel., made from titanium and magnesium
Frozen Methane - another power source? maybe put only on alien planet or mars or the titan moon.
Potassium Nitrate - should be found in 'caves'. i.e placed underground near ice sources., used in explosives.
These obviously have multiple uses, and can be mixed to create things like explosives,
Also for example, computers should require gold and a metal alloy (not iron). and copper can be used to create wiring components for the smaller sized functional blocks like cockpits and such.
Feel free to comment if you have anything to add. I keep saying its Space Engineers, space being the vast expanse including planets and the unknown, and then engineers, which is what this idea is focused on, you would need to visit the alien planet for 'frozen methane' and only earth would have 'coal' for the blast furnace to smelt iron ore. so building a larger ship would require you go to/from the planets essentially and you would need titanium and magnesium to build titanium plates to use in creating heavy armor. and making light armor from aluminum would give it another feeling of 'armor'... or possibly just add different tiers of armor blocks, light, medium, heavy, or aluminum, steel, titanium.
(i think many would like this idea)
