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 · Pure Mechanics
Treasure's Mega Drive boss-rush gauntlet demanding flawless execution against giant setpieces.

Execution · Pure Mechanics
Precision 3D platformer of narrow corridors, crates, and unforgiving jumps.
Alien Soldier leans Execution (Pure Mechanics); Crash Bandicoot leans Execution (Pure Mechanics).
Alien Soldier leans a little harder on execution, though the gap is small.
Alien Soldier
Frame-tight dodges across thirty-plus bosses
Crash Bandicoot
Tight jumps on narrow paths punish slop
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Soldier
Bosses fully scripted
Crash Bandicoot
Hazards are fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Soldier
Nothing hidden after one loop
Crash Bandicoot
Everything scripted and placed
Alien Soldier leans a little harder on optimization, though the gap is small.
Alien Soldier
Weapon loadout and moveset mastery solvable
Crash Bandicoot
Box routes and gem requirements are learnable
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.
