Make IC², vanilla and new ores [Silver, other suggested ores] spawn at nether/end, making players explore more the new dimensions.
This making the nether/end not a fantasy dimension, but a continuation of overworld underground , "never" explored by man.
Only thing is that nether/end generation would have to be altered highly, is this possible to code?
Actually my idea is to make only layers 128- 258 (above nether bedrock) generation altered to make a continuation for overworld underground.
Or the whole end dimension [and removing the enderdragon, SMP servers would use a converter tool to remove enderdragon?]
To reach deep underground you would have to fall into void in the overworld (and bedrock would have to be changed into obsidian or something like)
deep underground stones would have an increased hardness [about 3-4 times harder],
ore veins would be bigger and more common,
lava would be even more common,
players drowns (loses air) in this dimension due lack of (good)air, [unless protected with Anti-hazard suit]
players take heat damage every X second due earth heat. [same as above]
Common Antihazard suit (rubber) lasts for 15 minutes before deterioration, this needing to be replaced.
Advanced Antihazard suit (quantum suit) lasts for 1h before energy depletes, this needing to be recharged.
IC² stuff behavior would have to be altered due higher temperature as:
Nuclear reactor heats instead of cooling inside deep underground.
Geothermal generator and generator efficiency gets increased by X%
New item: Iridium drill
_I_
IDI
ILI
I = Iridium plates
D = Diamond drill
L = lapotron crystal
Iridium drill works about 1.5x times faster than diamond drill
