Edit: This has evolved into a discussion on game balance concerning how difficult it is to obtain a metal versus how useful the metal is.
I've been thinking about the process of steel production. Let's review, shall we?
1. obtain ore
2. obtain fuel
3. create iron
4. (see 1-3)
5. obtain flux
6. create pig iron
7. (repeat steps 2 and 5)
9. create steel
Total material used: 2 iron ore, 4 fuel, 2 flux.
We go through all of this to make a metal that we can request in mass from the trade caravans. Some players are even skipping it to work with HFS. I don't know if a steel industry is worth it. It's hard. While I think I can say that DF players don't mind difficulty (losing is fun, after all), shouldn't there be some greater payoff for making such a difficult to obtain metal? We hardly need another super-metal, though, so why not simplify the process instead?
Now, imagine if it only took three smelter reactions: two to produce two bars of iron, one
1 to turn those bars into steel. You can't make anything out of pig iron anyway. The total cost in flux and fuel could remain the same, or the fuel cost could be reduced to thee. I think that might be more in line with steel's place in the current release.
I don't think I'm suggesting a big change, just a small one to streamline production. The difference would come in the form of less running back and forth to the bar stockpile to deposit/grab pig iron. If this gets support here, I'll take it to the suggestions forum.
If I've missed something, or if you disagree with me, don't hesitate to relieve me of ignorance.
1I realize you can simply mod in a smelter reaction to do this. The point of officially changing it is to comply with the rules of challenges that require you to use vanilla DF. [/i]
