Fallout: New Vegas asks more than The Sims, and the gap is execution.

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

Fallout: New Vegas leans Optimization (Pure Optimization); The Sims leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
The Sims
Clicking menus has no physical ceiling
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
The Sims

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
The Sims
Event rolls add flavour, all quickly mapped
Fallout: New Vegas leans clearly harder on optimization.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
The Sims
Need scheduling, career grinding and money loops are solvable
