head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
An economic engine puzzle about balancing production chains across island settlements.

Factory-meets-tower-defense; belts feed your defenses.
Dawn of Discovery leans Optimization (Pure Optimization); Mindustry leans Optimization (Pure Optimization).
Mindustry leans a little harder on execution, though the gap is small.
Dawn of Discovery
Pausable building keeps hands out of the equation
Mindustry
some tower placement under pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dawn of Discovery
AI traders and rivals follow predictable scripts
Mindustry
scripted enemy waves
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dawn of Discovery
Island fertilities and resources are unknown until scouted
Mindustry
map layout variation
Mindustry leans a little harder on optimization, though the gap is small.
Dawn of Discovery
Production chains and population-tier economics are the entire game
Mindustry
factory belts and logistics chains
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.
