Alright then, these are great ideas for biomes, I guess I should also include blocks and items to go alongside of it all.
here's a small list of blocks:
a small list of items:
Spoiler:
Crafting Items (includes some blocks listed first):
Log
Wood
Stone/Cobblestone
Sand
Sandstone
Tin bar (I name them bar instead of ingot)
Iron bar
Steel bar
Titanium bar
Space Metal bar (as said in the block section, I don't know what to call it)
Block Items:
Lever
Switch (same as above except smaller)
Wood/Stone/Metal Button
Wood/Stone/Metal Pressure Plate
Wires (tin being the worst and space metal wires being the best, replaces redstone)
Torch (Unlike Minecraft, if you hold this it still emits light)
Light (Various types, such as light poles, lamps, ect.) Requires electricity
Generators:
Motor (You must have a generator to make electricity, fueled by coal, wooden things, and gas)
Windmill (Requires wind)
Watermill (Requires water)
Solar Panel (Requires sunlight + space metal, but produces a lot of energy)
Batteries (All of which can be recharged, of course we get the small/medium/large/ect.)
Tools/Weapons/Armors:
The only exception to metal tools are gold and silver, these are considered in the same category as gems.
Gems are considered as currency, depending on where you are some gems are worth more.
If some of this seems out of place, it's because this revolves around multiple timeline options, you aren't just fixed to one time period.
You are free to suggest anything else that you might want in the game, of course it may take a while to add some, but all the good ideas will be added for sure.
Don't Suggest things that are FAR out of reach, I know I did, but it's so no one else suggests something to replace redstone. (Not sure if anyone was, but just for in case)
