Building comparison
head to head
Minecraft: Java EditionvsScrap Mechanic
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Minecraft: Java Edition
Optimization · Pure Optimization
An open sandbox where mastering crafting and building systems dominates over any physical skill.
Scrap Mechanic
Optimization · Pure Optimization
A creative engineering sandbox where machines built from logic and bearings do the heavy lifting.
Minecraft: Java Edition leans Optimization (Pure Optimization); Scrap Mechanic leans Optimization (Pure Optimization).

Axis by axis
Execution2 vs 3
Scrap Mechanic leans a little harder on execution, though the gap is small.
Minecraft: Java Edition
barely relevant, building/PvP negligible for most
Scrap Mechanic
Basic movement and combat; building is unhurried.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft: Java Edition
no adaptive opponent, sandbox play
Scrap Mechanic
Robot enemies are scripted and predictable.
Variance3 vs 3
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft: Java Edition
world gen and mob spawns randomized
Scrap Mechanic
Survival mode loot and world generation add some randomness.
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Minecraft: Java Edition
redstone, base/resource routing solvable systems
Scrap Mechanic
Logic gates, bearings and farm automation reward pure engineering.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
