A mod based around the critically-acclaimed anime: Fullmetal Alchemist; Would be an amazing mod to have.
I do realize the mod has already been done, but it is in 1.5, and the author seems to have stopped development.
It should have armor, such as:
It should have chalk! And special kinds of Alchemy!
There should be a way to get a Philosopher's stone, (like, using 9 nether stars or something).
Random NPC Soldiers!
Random NPC Ishvalans!
Random NPC State Alchemists!
Summoning Homunculi (Which will be a boss) by "attempting" human transmutation.
Randomly generated cities, villages, and ruins!
AUTOMAIL ARMS AND LEGS!! AUTOMAIL!!!
FATHER AS THE FINAL BOSS!
Equivalent Exchange Alchemy!
I would really love to see this mod come to life, so if any developer wants to take a shot at this project, please link the final product to me!
