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

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

Execution · Practiced Mastery
Retro co-op hack-and-slash about kiting monster floods through castle floors.
Grand Theft Auto V leans Execution (Practiced Mastery); Hammerwatch leans Execution (Practiced Mastery).
Hammerwatch leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Hammerwatch
Kiting hordes and dodging projectiles
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Hammerwatch
Enemy spawners follow fixed logic
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.
Hammerwatch
Secrets hidden until the map is learned
Hammerwatch leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Hammerwatch
Class builds, vendor economy, and secret routes
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.
