Industrial Revolution 3

IR3 is a remix/overhaul of IR2 (2020). It might be a momentary diversion for folks who:

Aren't challenged by launching vanilla rockets any more and want a slower, longer and quirkier game;
Need more crafting and materials complexity without it getting bonkers or feeling like a chemistry lecture;
Like things to be pretty and nice.

New or changed features

Gas and steam fissures: rare natural resources with rich output that ebbs and peaks.
Oil processing and hydrocarbons overhaul: continue cracking oil products down to natural gas and hydrogen; bitumen; ethanol; coke gasification.
Liquid fuel generator: generate power directly from flammable fluids.
Cryogenics: distil pure liquid oxygen, nitrogen, and helium from the atmosphere; liquefy or boil elemental gases.
Forestry overhaul: manage real trees as resources and protect them from pollution disasters; boost production with fertiliser.
Furnaces: gas furnaces run on natural gas; blast furnaces specialise in iron, steel, and metal foam production; arc furnace overhaul.
Geothermal exchange: use polluted steam from fissures to boil clean water.
Small assemblers and barrelling machines: 1x1 crafting machines that can handle a subset of small component recipes.
Bronze telescope: steam-powered radar; same sector scanning range as electric radar but a smaller area reveal.
Waterfill explosives: extend existing water tiles.
Fewer materials and tiers than IR2 but more components; gems are no longer mined from ores; rocket launches reworked.
Pollution and anti-pollution were rebalanced.
New QOL settings and gimmicks.

A metric buttload of original sprites and animations. That's 0.9 imperial buttloads.
Extended early game burner/steam phase, where getting to electricity and iron-working is the goal (skippable in map options).
New materials such as tin, rubber, glass, bronze, gold, lead, and chrome.
Internal component/processes generator, including crushing, ore washing, alloying, metal-casting, electroplating.
New machines, vehicles, and equipment, including primitive construction bots from almost the start of the game.
Great big drills from day one, because who likes building mining outposts anyway.
Built-in status lights on most electric machines, without any UPS-eating scripts.
Trains, vehicles and personal equipment that can run on rechargeable batteries.
A personal fuel manager that will automatically top up fuel in your power suit generators and vehicle.
Expanded defence options, including additional turret types and reinforced walls.
Scrapping system for recycling unwanted products.
Proper teleporters with proper balance and things that go "wom wom wom".
Easily missable details like recipe-based building damage shrapnel.
