head to head
Mindustry asks more than Fallout: New Vegas, and the gap is optimization.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.

Optimization · Pure Optimization
Factory-meets-tower-defense; belts feed your defenses.
Fallout: New Vegas leans Optimization (Pure Optimization); Mindustry leans Optimization (Pure Optimization).
Fallout: New Vegas leans a little harder on execution, though the gap is small.
Fallout: New Vegas
Shooter inputs with VATS assist
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.
Fallout: New Vegas
Scripted factions and enemies
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.
Fallout: New Vegas
Some loot and crit RNG
Mindustry
map layout variation
Mindustry leans clearly harder on optimization.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
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.
