head to head
Grand Theft Auto V asks more than ReCore, and the gap is reads.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.

Execution · Practiced Mastery
Colour-matching gunplay and platforming over a companion-build system.
Grand Theft Auto V leans Execution (Practiced Mastery); ReCore 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.
Grand Theft Auto V
Driving and shooting demand decent inputs.
ReCore
Colour-matched shooting and dash-platforming need moderate aim
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
ReCore
Robotic enemies follow fixed behaviour loops
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
ReCore
Dungeons and spawns are static
ReCore leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
ReCore
Core swapping, companion builds and collectible routing reward planning
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.
