head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Superhero sequel adding melee combat and a karma-split power arsenal in New Marais.

Execution · Practiced Mastery
Visceral hack-and-slash movie tie-in where Wolverine shreds everything in reach.
inFamous 2 leans Execution (Practiced Mastery); X-Men Origins: Wolverine leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
inFamous 2
Faster combat with melee and aimed powers
X-Men Origins: Wolverine
Lunge timing and combo flow carry brawls.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
inFamous 2
Scripted enemy factions, no adaptation
X-Men Origins: Wolverine
Enemies attack on fixed scripts.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
inFamous 2
Static world, fixed encounters
X-Men Origins: Wolverine
Almost none; encounters are staged.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
inFamous 2
Karma-gated power trees shape the run
X-Men Origins: Wolverine
Mutagen builds and skill unlocks are simple to solve.
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.
