Fire Emblem: Three Houses leans Optimization (Pure Optimization); Mindustry leans Optimization (Pure Optimization).
Mindustry leans clearly harder on execution.
Fire Emblem: Three Houses
Menu-driven, no mechanical bar
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.
Fire Emblem: Three Houses
AI follows fixed aggression rules
Mindustry
scripted enemy waves
Fire Emblem: Three Houses leans a little harder on variance, though the gap is small.
Fire Emblem: Three Houses
Hit rates and crit RNG affect runs
Mindustry
map layout variation
Mindustry leans a little harder on optimization, though the gap is small.
Fire Emblem: Three Houses
Class routing and build planning dominates
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.
