http://www.minecraftforum.net/topic/1540010-equivalent-exchange-3-pre1h/ Something like that mod would suffice. It's annoying when you mine and end up with a limitless supply of worthless dirt gravel and rock! A mechanic that would ensure nothing goes to waste would be nothing less than revolutionary!
Use it in thier faces! Like "BAM! How did U like the taste of Forbidden Alchemy in YOU' face, loosah! OOOOOOOHHHHHH!". Seriously If U have never tried the Equivalent Exchange mod on MInecraft, quit looking at this post insall the mod (if U do not know how to install mods, U are missing out on some crazy "PC Gamer Master Race" privleges!) and play Minecraft. I'm not giving the link to the mod since all U need is to scroll upwards! If U are the devs, and U got no clues of what I am talking about- the general idea: and P.S. The equivalent exchange mod bassically allows U 2 practice forbidden alchemy... if U have diamonds, like hundreds, and hundreds of diamonds. And Forbidden Alchemy? Sorry but my limited internet connection don't allow me to watch a lot of anime, or anythig else for that matter... so what were U referencing Ctc9592?
Well from what I know of Alchemy (By "Know" I mean what I watched of FMA) I don't think much of this would work because it would over power whoever got it. Now if we did the FMA route then that might work since it ACTUALLY requires Equivalent exchange in that mod it isn't equivalent exchange.
From the looks of that mod it seems less what alchemy was and more like magic. No Magic. Actual alchemy would be fine, tho.
