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

Optimization · Pure Optimization
A cozy island life-sim about building a community at your pace.

Optimization · Systems & Chaos
A time-travel mystery testing deduction of fixed cause-and-effect puzzle chains.
Animal Crossing: New Horizons leans Optimization (Pure Optimization); Time Hollow leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Animal Crossing: New Horizons
Trivial inputs.
Time Hollow
Drawing portals with the stylus is trivial
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Animal Crossing: New Horizons
NPCs are scripted.
Time Hollow
A fixed mystery plot, no adversary
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Animal Crossing: New Horizons
Daily visitors and fossils randomize.
Time Hollow
Story twists are hidden information on first play
Animal Crossing: New Horizons leans a little harder on optimization, though the gap is small.
Animal Crossing: New Horizons
Turnips, layout, and time-routing reward planning.
Time Hollow
Deducing where and when to open portals is fixed-solution puzzling
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.
