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
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Execution · Practiced Mastery
A faithful beat-em-up revival testing combo execution and pattern knowledge across escalating Foot Clan gauntlets.
Grand Theft Auto V leans Execution (Practiced Mastery); TMNT: Shredder's Revenge leans Execution (Practiced Mastery).
TMNT: Shredder's Revenge leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
TMNT: Shredder's Revenge
Tight combo windows, taunt timing, and boss parries demand execution
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
TMNT: Shredder's Revenge
All enemies are scripted; no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto V
Some mission and lobby randomness.
TMNT: Shredder's Revenge
Enemy placement is fixed per stage
TMNT: Shredder's Revenge leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
TMNT: Shredder's Revenge
Character unlocks, DX move mastery, and score routing reward knowledge
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.
