head to head
Fallout: New Vegas asks more than Anno 2070, and the gap is execution.

Optimization · Pure Optimization
A futuristic city-builder where eco and industrial factions race to settle a flooded Earth.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Anno 2070 leans Optimization (Pure Optimization); Fallout: New Vegas leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Anno 2070
Building and routing, no reflexes
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 2070
Faction AI is scripted
Fallout: New Vegas
Scripted factions and enemies
Fallout: New Vegas leans a little harder on variance, though the gap is small.
Anno 2070
Map generation varies resources slightly
Fallout: New Vegas
Some loot and crit RNG
Anno 2070 leans a little harder on optimization, though the gap is small.
Anno 2070
Eco-versus-industry chains reward exact balancing
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.
