head to head
SteamWorld Dig 2 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 mining metroidvania about digging efficient tunnels, hauling ore, and compounding upgrades.
Grand Theft Auto V leans Execution (Practiced Mastery); SteamWorld Dig 2 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.
SteamWorld Dig 2
Light platforming and digging dexterity
Grand Theft Auto V leans a little harder on reads, though the gap is small.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
SteamWorld Dig 2
Scripted enemies only
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.
SteamWorld Dig 2
Procedural ore pockets add mild run-to-run unknowns
SteamWorld Dig 2 leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
SteamWorld Dig 2
Dig routing, resource economy, and upgrade ordering are the game
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.
