head to head
Fallout: New Vegas asks more than Anno 1602, and the gap is execution.

Optimization · Pure Optimization
Island colonisation strategy about balancing population tiers against expanding supply chains.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Anno 1602 leans Optimization (Pure Optimization); Fallout: New Vegas leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Anno 1602
Slow real-time pace; no dexterity test.
Fallout: New Vegas
Shooter inputs with VATS assist
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Anno 1602
AI rivals act on fixed personalities, not adaptation.
Fallout: New Vegas
Scripted factions and enemies
Anno 1602 leans a little harder on variance, though the gap is small.
Anno 1602
Island fertility layouts and rival starts are hidden initially.
Fallout: New Vegas
Some loot and crit RNG
Anno 1602 leans a little harder on optimization, though the gap is small.
Anno 1602
Population tiers and supply chains are a near-pure logistics solve.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
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.
