head to head
Fallout: New Vegas asks more than Crayon Physics Deluxe, and the gap is execution.

Optimization · Pure Optimization
Draw crayon shapes that become physics objects to roll a ball to a star.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Crayon Physics Deluxe leans Optimization (Pure Optimization); Fallout: New Vegas leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Crayon Physics Deluxe
Freehand drawing needs only rough motor control
Fallout: New Vegas
Shooter inputs with VATS assist
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Crayon Physics Deluxe
No opponent exists
Fallout: New Vegas
Scripted factions and enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crayon Physics Deluxe
Physics wobble makes contraptions slightly unpredictable
Fallout: New Vegas
Some loot and crit RNG
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crayon Physics Deluxe
Each level rewards inventing an efficient contraption
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.
