head to head
Star Wars: The Old Republic asks more than Grand Theft Auto V, and the gap is optimization.

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

Optimization · Practiced Mastery
A narrative-heavy MMORPG where class rotation optimisation matters in raids and PvP warzones.
Grand Theft Auto V leans Execution (Practiced Mastery); Star Wars: The Old Republic leans Optimization (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.
Star Wars: The Old Republic
Operation combat has moderate GCD management and positional demands
Star Wars: The Old Republic leans a little harder on reads, though the gap is small.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Star Wars: The Old Republic
PvP warzones feature real adaptive opponents
Star Wars: The Old Republic leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Star Wars: The Old Republic
Gear drop RNG is present but secondary to ability knowledge
Star Wars: The Old Republic leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Star Wars: The Old Republic
Advanced class ability rotations and set bonus builds are solvable
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.
