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

Execution · Practiced Mastery
Moderate action combat wrapped around weighty authored choices.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Banishers: Ghosts of New Eden leans Execution (Practiced Mastery); Grand Theft Auto V 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.
Banishers: Ghosts of New Eden
Dodge and swap timing in action combat is moderate
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans a little harder on reads, though the gap is small.
Banishers: Ghosts of New Eden
Spectral enemies follow fixed attack patterns
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Banishers: Ghosts of New Eden
Haunting cases are authored, not randomised
Grand Theft Auto V
Some mission and lobby randomness.
Banishers: Ghosts of New Eden leans a little harder on optimization, though the gap is small.
Banishers: Ghosts of New Eden
Gear upgrades, character swapping and decision routes are learnable
Grand Theft Auto V
Heists, money loops, builds learnable.
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.
