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

Optimization · Pure Optimization
A physics construction puzzler about building cost-efficient structures to guide an armadillo.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Armadillo Run leans Optimization (Pure Optimization); Fallout: New Vegas leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Armadillo Run
Building structures has no twitch requirement
Fallout: New Vegas
Shooter inputs with VATS assist
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Armadillo Run
No opponent; pure physics sandbox
Fallout: New Vegas
Scripted factions and enemies
Fallout: New Vegas leans a little harder on variance, though the gap is small.
Armadillo Run
Physics is deterministic once a structure is built
Fallout: New Vegas
Some loot and crit RNG
Armadillo Run leans a little harder on optimization, though the gap is small.
Armadillo Run
Designing efficient physics structures within budget is the whole 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.
