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

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

Execution · Practiced Mastery
Co-op horde shooting spiced with traps and learnable relic puzzles.
Grand Theft Auto V leans Execution (Practiced Mastery); Strange Brigade leans Execution (Practiced Mastery).
Strange Brigade leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Strange Brigade
Horde shooting and trap timing need steady aim
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Strange Brigade
Mythological hordes are scripted spawns
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.
Strange Brigade
Relic placements and puzzle rotations vary slightly
Strange Brigade leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Strange Brigade
Trap usage, amulet builds and puzzle solutions 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.
