Conjure items from nothingness using energy and a bit of magic. Or sufficiently advanced technology, who really knows?
Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!
New Ores and resources as well as machines.
Things related to oil and other fluids.
Furnaces, assembling machines, production chains.
I'm just surprised that we can summon pre-processed tungsten, holmium, and lithium, but we can't summon carbon fiber.
And also that we can't summon the special yumako & jellynut landfill.
Good additions for 1.5!
Also a summon for fish, because if we can't summon spidertrons wholesale (Would be hilarious if we could), it would be nice to not have to do fish breeding for it.
