Fallout: New Vegas
Scripted factions and enemies
The Swapper

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
The Swapper
Clone-placement puzzles have fixed solvable solutions
