head to head
Fallout: New Vegas asks more than Loom, 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 musical adventure where learning and reversing melodic spells forms a closed combinatorial puzzle system.
Fallout: New Vegas leans Optimization (Pure Optimization); Loom leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Loom
Musical spell sequences require accurate note input under light pressure
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
Loom
Fantasy narrative with scripted antagonists
Fallout: New Vegas leans a little harder on variance, though the gap is small.
Fallout: New Vegas
Some loot and crit RNG
Loom
Deterministic world with no randomised elements
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Loom
Learning and combining distaff spells in the correct order is a fully solvable logic system
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.
