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

Optimization · Pure Optimization
A roguelite dungeon-crawler fused with a cult management sim.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Cult of the Lamb 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.
Cult of the Lamb
Roguelite combat needs decent dodges.
Fallout: New Vegas
Shooter inputs with VATS assist
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Cult of the Lamb
Enemies are scripted, not adaptive.
Fallout: New Vegas
Scripted factions and enemies
Cult of the Lamb leans clearly harder on variance.
Cult of the Lamb
Run rooms and tarot pulls randomize.
Fallout: New Vegas
Some loot and crit RNG
Fallout: New Vegas leans a little harder on optimization, though the gap is small.
Cult of the Lamb
Cult management and build synergies dominate.
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.
