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.

Optimization · Practiced Mastery
A four-player Wii Kirby romp gathering ship parts for the stranded alien Magolor.

Optimization · Pure Optimization
LEGO romp through the original Indy trilogy's set pieces and puzzles.
Kirby's Return to Dream Land leans Optimization (Practiced Mastery); LEGO Indiana Jones: The Original Adventures leans Optimization (Pure Optimization).
Kirby's Return to Dream Land leans a little harder on execution, though the gap is small.
Kirby's Return to Dream Land
Easygoing main game; EX mode adds modest demands
LEGO Indiana Jones: The Original Adventures
Whip swings and brawls, very forgiving
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby's Return to Dream Land
Bosses are pattern-scripted
LEGO Indiana Jones: The Original Adventures
Scripted foes and traps
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby's Return to Dream Land
Energy sphere hiding spots are static secrets
LEGO Indiana Jones: The Original Adventures
Everything placed deterministically
LEGO Indiana Jones: The Original Adventures leans a little harder on optimization, though the gap is small.
Kirby's Return to Dream Land
Super ability timing and sphere collection are solvable
LEGO Indiana Jones: The Original Adventures
Item and character gating across replayable levels
