head to head
Grand Theft Auto V asks more than Mass Effect: Andromeda, and the gap is reads.

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

Execution · Practiced Mastery
Open-galaxy entry whose mobile combat outshines its exploration loop.
Grand Theft Auto V leans Execution (Practiced Mastery); Mass Effect: Andromeda 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.
Mass Effect: Andromeda
jump-jet mobility raises the combat ceiling
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Mass Effect: Andromeda
kett follow fixed AI routines
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.
Mass Effect: Andromeda
exploration surprises only on first visit
Mass Effect: Andromeda leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Mass Effect: Andromeda
profile swapping and research crafting systems
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.
