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

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

Optimization · Pure Optimization
Coordinating three characters through fixed object-logic puzzles.
Fallout: New Vegas leans Optimization (Pure Optimization); The Cave leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
The Cave
Undemanding platforming with no timing pressure
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
The Cave
No adversary - a narrating cave is not a mind
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 Cave
Each character's section is unknown on first descent
Fallout: New Vegas leans clearly harder on optimization.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
The Cave
Three-character object-shuffling puzzles are the whole game
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.
