head to head
Fallout: New Vegas asks more than The Talos Principle 2, and the gap is execution.

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

Optimization · Pure Optimization
A deeper extension of the original spatial logic with more elaborate multi-tool puzzles.
Fallout: New Vegas leans Optimization (Pure Optimization); The Talos Principle 2 leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
The Talos Principle 2
Environmental traversal imposes negligible physical demands
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
The Talos Principle 2
No opponent; isolated puzzle solving throughout
Fallout: New Vegas leans clearly harder on variance.
Fallout: New Vegas
Some loot and crit RNG
The Talos Principle 2
Puzzles are fully deterministic with no randomness
The Talos Principle 2 leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
The Talos Principle 2
Expanded connector and accumulator mechanics require exact logical sequencing
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.
