head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
Alternate-history alien-invasion shooter known for its inventive Chimeran arsenal.

Execution · Competitive PvP
Reversal-timing duels dressed in wrestling spectacle, with light opponent prediction.
Resistance: Fall of Man leans Execution (Practiced Mastery); WWE 2K14 leans Execution (Competitive PvP).
Resistance: Fall of Man leans a little harder on execution, though the gap is small.
Resistance: Fall of Man
Aim and weapon handling against Chimera hordes.
WWE 2K14
Reversal timing windows are the main physical test
WWE 2K14 leans a little harder on reads, though the gap is small.
Resistance: Fall of Man
Sizable competitive multiplayer added genuine human opposition.
WWE 2K14
Human opponents bait reversals; AI is mappable
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Resistance: Fall of Man
Campaign unknowns on first pass.
WWE 2K14
Comeback mechanics add scripted swing
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Resistance: Fall of Man
Exotic weapon selection per encounter rewards system knowledge.
WWE 2K14
Knowing move properties and match-type rules pays off
