Faster combat demanding strafing and aim precision.

Donkey Kong 64
Scripted bosses and enemies
Ratchet & Clank: Up Your Arsenal
Campaign is scripted; legacy multiplayer added a thin PvP layer.

Donkey Kong 64

Ratchet & Clank: Up Your Arsenal
Unknown encounters only on first playthrough.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong 64
