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

Optimization · Pure Optimization
Touch-controlled DS Zelda centered on re-running a timed stealth dungeon ever faster.

Optimization · Pure Optimization
Solving designed encounters through party builds and pause-driven tactical positioning.
The Legend of Zelda: Phantom Hourglass leans Optimization (Pure Optimization); Tower of Time 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.
The Legend of Zelda: Phantom Hourglass
Stylus controls are simple and forgiving
Tower of Time
Real-time pause combat needs some micro, never twitch mastery
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Legend of Zelda: Phantom Hourglass
Phantoms patrol fixed routes
Tower of Time
Enemy waves are scripted encounters
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
The Legend of Zelda: Phantom Hourglass
Sea exploration unknowns first run
Tower of Time
Dungeon contents are fixed once seen
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Legend of Zelda: Phantom Hourglass
Temple of the Ocean King rewards optimized repeat routing
Tower of Time
Party builds, skill synergies and time-manipulation tactics solve 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.
