i agree with proloe his/her (i cannot tell and i never assume) mod cannot be submitted since it is a pre-existing mod besides it would have an unfair advantage if it were to be posted it likely has many followers (like that cheater pack joliween) so it would get votes for familliarity (i bet it is a good mod but i just dont like steampunk things in a medieval world and i am using millenaire and Tale of Kingdoms) if i wernt using those 2 mods i would likely be using Steamcraft, IC2, Buildcraft, and Equivalent Exchange (i like those mods i have a separate .minecraft folder just for them minus steamcraft) damnit i went and rambled again.
lol look it up and you'll see. The most I can say its a cross between fantasy and scifi which formed its own genre. Its more scifi though. It's an awesome genre you should look it up. If someone were to make a mod it had better be steampunk xD because if I just see a bunch of brown and no steam I'm going to be disappointed.
