Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Pokémon Ruby Version

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas

Fallout: New Vegas
Some loot and crit RNG
Pokémon Ruby Version
Encounter, catch and crit rolls are quickly mapped
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Faction routing, perks, builds heavily rewarded
Pokémon Ruby Version
