head to head
Overlord 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 darkly comic action game where you herd colour-coded minion hordes as an evil overlord.
Grand Theft Auto V leans Execution (Practiced Mastery); Overlord leans Optimization (Practiced Mastery).
Grand Theft Auto V leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Overlord
Sweeping minion hordes takes modest 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.
Overlord
Scripted heroes and creatures
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Overlord
Fixed level design
Overlord leans clearly harder on optimization.
Grand Theft Auto V
Heists, money loops, builds learnable.
Overlord
Minion type usage and upgrade economy reward planning
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.
