About Love, Hate and the other ones
Minor timing on character movement, never twitch-defining
Fallout: New Vegas
Shooter inputs with VATS assist
Fallout: New Vegas leans a little harder on reads, though the gap is small.
About Love, Hate and the other ones
Solo puzzler - no opponent to predict
Fallout: New Vegas
Scripted factions and enemies
Fallout: New Vegas leans a little harder on variance, though the gap is small.
About Love, Hate and the other ones
Behaviours are fixed once learned, nothing random
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.
About Love, Hate and the other ones
Solving each level's logic puzzle is the entire game
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.
