I've been thinking about how cool it would get if it was possible to make metal alloys such as steel - iron and coal/CO2 and other alloys that consist of a metal and non-metal. I know that for this more metallic and non-metallic elements would have to be added (possibly metalloids too) but it would be very much worth it!

On the other hand, there could just be alloys themselves added instead of you doing the work. But you could have the option to either make them yourself or not bother and just get already as an element. However, there could be more possibilities of creations people could make like blast furnaces. Also electrolysis is no more than 'some hazy ideal of realism' but has been added in so there isn't much reason to argue...

Yea I think I'll try that but that's the only thnig you can do. Right?

I don't exactly know what script and how to make it but OK WATEVR

I don't think I can run Lua...don't bother :P
