head to head
Fallout: New Vegas asks more than Braid, and the gap is variance.

Optimization · Pure Optimization
A platformer puzzle game built around deducing and exploiting each world's unique time-manipulation rule.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Braid leans Optimization (Pure Optimization); Fallout: New Vegas leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Braid
Precise jumps and time-rewind timing are load-bearing
Fallout: New Vegas
Shooter inputs with VATS assist
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Braid
No opponent; solo platforming puzzle
Fallout: New Vegas
Scripted factions and enemies
Fallout: New Vegas leans clearly harder on variance.
Braid
All puzzles are deterministic and hand-crafted
Fallout: New Vegas
Some loot and crit RNG
Braid leans a little harder on optimization, though the gap is small.
Braid
Understanding each world's time-manipulation rule and its exact solution is the game
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.
