head to head
Inazuma Eleven Strikers 2012 Xtreme asks more than Grand Theft Auto V, and the gap is reads.

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

Optimization · Practiced Mastery
An arcade soccer RPG testing timed special moves and team building.
Grand Theft Auto V leans Execution (Practiced Mastery); Inazuma Eleven Strikers 2012 Xtreme leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Driving and shooting demand decent inputs.
Inazuma Eleven Strikers 2012 Xtreme
Timed inputs for shots and tackles need moderate skill
Inazuma Eleven Strikers 2012 Xtreme leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Inazuma Eleven Strikers 2012 Xtreme
Versus matches involve reading opponent movement
Inazuma Eleven Strikers 2012 Xtreme leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Inazuma Eleven Strikers 2012 Xtreme
Special-move outcomes and matchups add some chaos
Inazuma Eleven Strikers 2012 Xtreme leans clearly harder on optimization.
Grand Theft Auto V

Inazuma Eleven Strikers 2012 Xtreme

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.
