Fallout: New Vegas leans clearly harder on execution.
Danganronpa 2: Goodbye Despair
Mini-game trial mechanics add light timing demands
Fallout: New Vegas
Shooter inputs with VATS assist
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Danganronpa 2: Goodbye Despair
Killers are scripted; no opponent models the player
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.
Danganronpa 2: Goodbye Despair
Hidden motive and evidence obscure each culprit
Fallout: New Vegas
Some loot and crit RNG
Fallout: New Vegas leans clearly harder on optimization.
Danganronpa 2: Goodbye Despair
Linking clues into the decisive argument chain is repeatable and solvable
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
