head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Practiced Mastery
Series finale blending stealth with active battlefields and heavy cinematics.

Optimization · Practiced Mastery
A squad-based Star Wars shooter where commanding your clone team wins battles.
Metal Gear Solid 4: Guns of the Patriots leans Optimization (Practiced Mastery); Star Wars: Republic Commando leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Solid 4: Guns of the Patriots
flexible gunplay alongside sneaking
Star Wars: Republic Commando
Solid gunplay but squad does much lifting
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Solid 4: Guns of the Patriots
battlefield factions act on scripts
Star Wars: Republic Commando
Droid AI follows fixed behaviours
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Gear Solid 4: Guns of the Patriots
mid-battle chaos mostly cosmetic
Star Wars: Republic Commando
Encounters are scripted and repeatable
Star Wars: Republic Commando leans a little harder on optimization, though the gap is small.
Metal Gear Solid 4: Guns of the Patriots
camo, gear, and route knowledge per act
Star Wars: Republic Commando
Squad positioning and order timing decide fights
