The last few weeks i've been playing a lot of terrafirmacraft, my general view about the mod is that it has more content than vs(but most of the stuff that is in vs is just better) and it has addons that are better than vs mods in my view, anyway by playing tfc i noticed that steel in vs is boring, in tfc for you to make steel you make a blast furnace, quickly proccess it into pig iron, and then you work it twice to make steel, and to make 2 more tool tiers you can alloy it with some stuff to make colored steel, of wich you combine a whole ingot of it with a whole ingot of pig iron (so 1 colored steel is 2 iron) and then you can do that again to make a better colored steel, but in vs you simply make a furnace and put 16 iron ingots in for like 3 days, my point is in tfc you are doing active work, how much steel you get depends on how much time you put into it, but in vs the only thing you can do is wait, or at the most get olivine and titanium to make maintenance of the furnace cheaper, i'm not advocating for vs to just copy paste tfc's steel but i think it would be a lot more fun for steel to have a more active making proccess.
oh and also one more interesting thing is that after steel you can just ignore iron, in tfc, and just use steel to make alll iron recipes but more efficiently, like if you use iron to make rails you need 3 ingots for 32 rails, but with steel you get 64 rails per 3 ingots.
