head to head
Fallout: New Vegas asks more than Golden Sun: Dark Dawn, and the gap is execution.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.

Optimization · Pure Optimization
Turn-based JRPG testing Djinn build optimisation and fixed Psynergy puzzles.
Fallout: New Vegas leans Optimization (Pure Optimization); Golden Sun: Dark Dawn leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Fallout: New Vegas
Shooter inputs with VATS assist
Golden Sun: Dark Dawn
Turn-based menu combat involves no dexterity
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
Golden Sun: Dark Dawn
Bosses run fixed scripts with no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Some loot and crit RNG
Golden Sun: Dark Dawn
Hidden Djinn locations are unknown only until found
Fallout: New Vegas leans a little harder on optimization, though the gap is small.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Golden Sun: Dark Dawn
Djinn class combinations and Psynergy puzzles are the solvable core
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.
