RisCraft Complete Edition

The early game has be revamped, and now is more focused on exploration and scavanging for supplies.
Rather than punching a tree to get wood, you now skip wooden tools alltogether.
You can now find sticks, rocks, and other goodies in the dirt below your feet. Dig for some rocks in the ground, and go RIGHT to stone tools! Then you can choose to focus more on gathering wood, or focus on mining for more resources. 
Wooden Tools are completly removed.
You also can now make campfires much easier, with the new campfire recipie. The campfire also will let you smelt ores at a much slower rate. And there are new campfire exclusive recipies. You also NEED at least one iron nugget and one coal to craft a furnace. So the campfire will have a use for longer.

Some mobs are now far more difficult, whilst others had their difficulty dialed back. (Also the difficulty is locked into Hard.)
There are also new mobs, as mentioned before, that you will routinely see.

THOUSANDS of new recipes have been added. Including recipes for times that dont actually have recipes. Mobs that did not have drops before, also have been given drops! And with new recipes comes new items and magic.
There are now new forms of magic and alchemy, that help you create SPAWN EGGS!
This both is a connivance, and saves you the pain of needing to port mobs from place to place.
You can now craft spawn eggs using magical ingredients in a basin or with a basic crafting table.
And the Carry-On, Leashed, and Leashable Collars mods are also added, making it EVEN EASIER to move mobs around.
