head to head
Grand Theft Auto V asks more than Contra: Rogue Corps, and the gap is reads.

Execution · Practiced Mastery
Twin-stick shooting throttled by an upgrade grind more than reflex ceilings.

Execution · Practiced Mastery
Sandbox crime playground spanning shooting, driving, and a persistent online economy.
Contra: Rogue Corps leans Execution (Practiced Mastery); Grand Theft Auto V leans Execution (Practiced Mastery).
Contra: Rogue Corps leans a little harder on execution, though the gap is small.
Contra: Rogue Corps
Twin-stick dodging and aim carry every firefight
Grand Theft Auto V
Driving and shooting demand decent inputs.
Grand Theft Auto V leans clearly harder on reads.
Contra: Rogue Corps
Enemy waves are scripted spawns, not minds
Grand Theft Auto V
Online PvP exists but mostly gear/positioning, not modeling.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Contra: Rogue Corps
Loot drops add mild noise to the grind
Grand Theft Auto V
Some mission and lobby randomness.
Contra: Rogue Corps leans a little harder on optimization, though the gap is small.
Contra: Rogue Corps
Weapon upgrades and build grinding gate progress heavily
Grand Theft Auto V
Heists, money loops, builds learnable.
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.
