An overhaul mod focusing on end-game technologies and moderately increased complexity.
Large total conversion mods.
Transportation of the player, be it vehicles or teleporters.
Augmented or new ways of transporting materials - belts, inserters, pipes!
Trains are great, but what if they could do even more?
New ways to deal with enemies, be it attack or defense.
Armors or armor equipment.
New Ores and resources as well as machines.
Things related to oil and other fluids.
Related to roboports and logistic robots.
Furnaces, assembling machines, production chains.
Changes to power production and distribution.
More than just chests.
Can you make an option or a mod to only use basic tech cards in research?
Like this one, but for Krastorio: https://mods.factorio.com/mod/OnlyRedsUpdated
I find it much more fun and less tedious to play with it.
Not likely, sorry. IMO that completely ruins the point of the game.
Feel free to make a patch mod to do this though.
I would like to, but I have zero experience in Factorio modding.
