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

Optimization · Pure Optimization
A tower-defense-style strategy game defending against alien comet invasions.

Optimization · Systems & Chaos
Puzzle adventure about coaxing a giant half-tame creature through ancient ruins.
Comet Crash 2: The Kronkoid Wars leans Optimization (Pure Optimization); The Last Guardian 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.
Comet Crash 2: The Kronkoid Wars
minimal direct control, mostly tactical placement
The Last Guardian
Slow climbing and platforming, very forgiving
Comet Crash 2: The Kronkoid Wars leans a little harder on reads, though the gap is small.
Comet Crash 2: The Kronkoid Wars
limited AI opponent adaptation
The Last Guardian
Trico is willful but not modeling you adversarially
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Comet Crash 2: The Kronkoid Wars
randomized comet and enemy spawns
The Last Guardian
Trico's unpredictable compliance adds noise
Comet Crash 2: The Kronkoid Wars leans a little harder on optimization, though the gap is small.
Comet Crash 2: The Kronkoid Wars
tower/unit placement strategy optimization
The Last Guardian
Environmental puzzles with intended solutions
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.
