So while I was at work yesterday, I came up with an idea to have a Journey to the Center of the Earth-style world, where pretty much everything is normal, but in a bunch of giant, interconnected caves. The ground level would all be at like 250 or something, to maximize the amount of "caveage."
Now on to the fun stuff. This will be my first mod, so I'm hoping to get a decent amount of support from you guys on this. I do have a fairly decent knowledge of Java from a college class I took in it this last year. All the same, I'll need as much help as you guys are willing to give me!
