Before Reading Notes

The following is a summary of core features, not a complete list: specific values are subject to the in-game 'View Rules' screen. Starting from 0.6.0, difficulty has been changed to a setCustomizable rules——When creating a world, choose Simple / Normal / Expert / Custom presets. Presets are just the default values for these rules. Select "Custom" or inconfig/gtocore-rules.txtJust modify item by item; the rules are written into the save file and locked when the world is created, and they will not change afterward.

Difficulty does not affect the main storyline or ending, only the challenge (recipes, machine values, and certain thresholds)!

Easy Mode

AE2 uses original recipes (no modifications)
ME network infinite channels
Boost steam / power generation capacity, increase power generation array machine capacity / turbine output
Increased upper and lower limits of maintenance pod time multiplier for load regulation
No clean room required
Increased yield / simplified for some recipes
(MV Stage) ME Simple Sample Assembly: Sample assembly with 9 sample slots
Assembly line does not require ordered input
Infinite storage for bedrock veins / bedrock fluid veins
Parallel control pod calculates parallel count based on one level higher
Increased parallel values for steam large machines
Increased maximum diggable quantity for chain mining
Large material supply for task books
Can enter the Overworld / Void dimension in the LV stage
General factory parallel doubled

Normal mode

AE2 comprehensive modification (initially unlocked at MV stage, automation enabled at HV stage)
ME network infinite channels
Monster enhancement (higher health, stronger attack, please handle with care)
Assembly line requires ordered input of items to work

Expert mode (Expert)

Harder AE2 overhaul (MV phase partially unlocked, EV phase enables automation)
ME network infinite channels
Monster enhancement (higher health, stronger attack, proceed with caution)
Steam / Power generation capacity reduction
Machines will explode if rained upon
Recipe output reduced / complicated
Maintenance chamber upper and lower limits reduced
Higher radio consumption
Insufficient energy while running machines will cause recipe interruption, progress reset to zero, and input materials will not be returned
Assembly lines require ordered input of items and fluids to function
Parallel control chambers have no level bonus (same as normal, lower than simple)
Power generation equipment will continue to generate power and destroy excess energy when the output chamber is full
The level of the sound dampening chamber installed on the machine must be the same as the voltage level or differ by ±1 level, otherwise it will not run
The giant turbine has an extra high-speed multiplier mode adjustment, allowing higher operating speed at the cost of faster rotor damage

Appendix: Complete Rules List

The table below is the complete rules registry.102rules, and their default values under three presets. The Rule ID isconfig/gtocore-rules.txtKey names used in; the rule values for the label 'Gear' can only beeasy / normal / expert，fill in the remaining values or boolean rules according to the format in the table (specific upper and lower limits can be seen in the "View Rules" interface within the game). SelectCustomAll 102 items can be modified in this mode; when selecting Easy / Normal / Expert, only the 'Don't go to Heaven Challenge' can be modified independently, while the rest follow the presets.
