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

Execution · Practiced Mastery
A simple licensed brawler testing little beyond button mashing and upgrades.

Optimization · Practiced Mastery
A forgiving family collect-athon testing completionist puzzle-solving.
Dragon Ball Z: Sagas leans Execution (Practiced Mastery); LEGO Star Wars II: The Original Trilogy leans Optimization (Practiced Mastery).
Dragon Ball Z: Sagas leans a little harder on execution, though the gap is small.
Dragon Ball Z: Sagas
Simple brawling needs only basic timing
LEGO Star Wars II: The Original Trilogy
Forgiving combat and platforming for all ages
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball Z: Sagas
Enemies and bosses are scripted
LEGO Star Wars II: The Original Trilogy
Enemies are trivial fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dragon Ball Z: Sagas
Linear levels with fixed encounters
LEGO Star Wars II: The Original Trilogy
Authored levels hold no real randomness
LEGO Star Wars II: The Original Trilogy leans a little harder on optimization, though the gap is small.
Dragon Ball Z: Sagas
Z-coin upgrades add a thin progression layer
LEGO Star Wars II: The Original Trilogy
Minikit hunting and ability-gated puzzles are the depth
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.
