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

Optimization · Pure Optimization
A gentle turn-based system easily solved by build and gear choices.

Optimization · Pure Optimization
Zelda-style puzzle dungeons and exploration with low-pressure combat.
South Park: The Stick of Truth leans Optimization (Pure Optimization); Star Fox Adventures leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
South Park: The Stick of Truth
Timed attack and block prompts add light input demands
Star Fox Adventures
Lock-on staff combat is deliberately forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
South Park: The Stick of Truth
Enemies follow fixed turn-based scripts
Star Fox Adventures
Dinosaurs and bosses are Rare-scripted patterns
South Park: The Stick of Truth leans a little harder on variance, though the gap is small.

Minor damage rolls; encounters are otherwise fixed
Star Fox Adventures
Dinosaur Planet is fixed and explorable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
South Park: The Stick of Truth
Build, gear and ability choices comfortably solve every fight
Star Fox Adventures
Zelda-style dungeon puzzles and item routing are the substance
