head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Practiced Mastery
Solving camera placement puzzles, then executing the watch-and-shoot plan under time pressure.

Optimization · Practiced Mastery
A squad-based Star Wars shooter where commanding your clone team wins battles.
Star Fox Guard 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.
Star Fox Guard
Snapping between camera feeds to shoot robots needs quick hands
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.
Star Fox Guard
Robot waves follow fixed scripted routes, nothing adapts
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.
Star Fox Guard
Wave compositions are unknown on first attempts only
Star Wars: Republic Commando
Encounters are scripted and repeatable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Star Fox Guard
Camera placement and wave memorisation solve each map
Star Wars: Republic Commando
Squad positioning and order timing decide fights
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.
