The mod, as the title suggests, adds the classic Equivalent Exchange philosopher's stone recipes from the beta times. That being said, you're allowed (not limiting!) smelting ores in crafting table with a bit of coal, creating twisted factories (id est, redstone factory originating from sugarcane farm), obtaining mob drops in peaceful mode and many other things.
The main goal of this project's existence is reviving a few aspects we (or at least I) used to enjoy. I believe, the unconventionality of EE1 will spark some creativeness into modern-day minecraft projects.
I can backport the mod to 1.12, 1.8 or any other version you'd like, just inbox me or write down in this thread. I'm also open for suggestions about the mod. The issues can be reported in the issues tab of the CurseForge project.
As a long-term goal, I plan on implementing aggregator and condenser functionalities. I don't think implementing the transmutation table is necessary, I plan on adding some of my own, (hopefully) cool stuff too, but now I'm waiting for some feedback.
It's my first attempt at modding something hopefully useful, so I'm open for tips aswell.
