I added a list of stuff I'm planning to do to the first post, in the spoiler at the bottom. I decided to change things quite a bit from the Minecraft version, since balance, thematics, and capabilities are very different in DF then in MC.
Like, for example, I'll be adding a kind of alchemical tech tree, where one must must first explore the world of alchemy and make discoveries before one can emulate real materials with any real efficiency. You can replicate real-world matter even at 'tier 1' (as of now, in my head, there are really only two tiers; Pre-Secret and Post-Secret, which I will refer to as such from now on). However, the reaction is highly inefficient, requiring twice as much EMC as the item actually costs EMC-wise in the real world. If I add more then 1 tier, the those will gradually increase this efficiency, but as of now pre-secret costs 2x as much, post-secret is true equivalent exchange.
I'll also be adding new 'Alchemical' materials, which are essentially inferior, but sometimes uniquely useful versions of their real-world counter-parts. These are much easier to produce pre-secret, having roughly the same cost as their counter-parts. There's a bit more info up in the spoiler, but I won't be revealing what I have planned for individual stuff yet... Where's the !!FUN!! in that? ;P
Another thing I'll be adding is EMC tiers, each being a more condensed form of the last, which can be condensed and broken apart freely at no additional cost. The more expensive stuff will require more condensed forms of EMC, and converting stuff with higher EMC values will also yield their equivalent EMC value. This should reduce clutter, hauling, and just generally make things easier to deal with...
Also, I am working on this now, but progress is rather slow, since I tend to be easily distracted...
Alsoalso, New Guy, that is glorious. Thank you telling me about that, that will make things a HELL of a lot easier... And it's not difficult to justify thematically, either.
EDIT: Oh, also, once I actually get something worth making a new thread about, I will do so, and probably rename the mod to "Secrets of Creation"
Internally, though, it'll still be abbreviated as EE.
EDIT2: Alsoalso, some help with the x to EMC reactions would help a lot, and be greatly appreciated. I've decided to stick with only converting raw materials (metal bars (not ore), wood, stone, gems, plants, corpses (including vermin). However, there are a few challenges with this... Like, for example, I plan on having the gems each have separate cost tiers, which are defined in the spoiler. But how can I do this, without adding a new reaction for every single gem?
