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

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

Execution · Practiced Mastery
Tests isometric jump precision and room-by-room spatial puzzle reading.
Grand Theft Auto V leans Execution (Practiced Mastery); Lumo leans Execution (Practiced Mastery).
Lumo leans a little harder on execution, though the gap is small.
Grand Theft Auto V
Driving and shooting demand decent inputs.
Lumo
Isometric jumps with tricky perspective punish imprecision
Grand Theft Auto V leans clearly harder on reads.
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Lumo
Rooms are fixed challenges with no opponent
Grand Theft Auto V leans a little harder on variance, though the gap is small.
Grand Theft Auto V
Some mission and lobby randomness.
Lumo
Secrets hide only until the room is studied
Lumo leans a little harder on optimization, though the gap is small.
Grand Theft Auto V
Heists, money loops, builds learnable.
Lumo
Each chamber is a solvable spatial puzzle
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.
