head to head
Gradius V asks more than Resident Evil 5, and the gap is optimization.

Optimization · Practiced Mastery
A formation-based horizontal shmup where managing your options configuration and memorising scripted enemy patterns is the game.

Execution · Practiced Mastery
Co-op action take on Resident Evil trading dread for set-piece gunfights.
Gradius V leans Optimization (Practiced Mastery); Resident Evil 5 leans Execution (Practiced Mastery).
Gradius V leans a little harder on execution, though the gap is small.
Gradius V
Maintaining power-up state through dense formation fire demands precision
Resident Evil 5
Action-heavy aiming and melee timing carry encounters
Resident Evil 5 leans a little harder on reads, though the gap is small.
Gradius V
All enemy patterns are scripted Konami-classic formations
Resident Evil 5
Co-op coordination, not adversarial prediction
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gradius V
Minimal; stages are nearly deterministic
Resident Evil 5
Mostly fixed encounters after first run
Gradius V leans clearly harder on optimization.
Gradius V
Options configuration, power-up sequencing, and checkpoint recovery are fully solvable
Resident Evil 5
Weapon upgrades and Mercenaries routing 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.
