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 · Systems & Chaos
Tests park economy management and team building under card-pack RNG.

Optimization · Pure Optimization
Lane-defense economy optimization against semi-randomised zombie waves.
Jurassic World: The Game leans Optimization (Systems & Chaos); Plants vs. Zombies 2: It's About 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.
Jurassic World: The Game
Timed taps in battles add a thin reflex layer
Plants vs. Zombies 2: It's About Time
Tapping plants quickly only matters in surge moments
Jurassic World: The Game leans a little harder on reads, though the gap is small.
Jurassic World: The Game
Battle rock-paper-scissors vs AI is mostly pattern, barely predictive
Plants vs. Zombies 2: It's About Time
Zombie waves are announced patterns, not minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Jurassic World: The Game
Card packs gate dinosaur acquisition behind RNG
Plants vs. Zombies 2: It's About Time
Wave compositions and plant-food drops add per-level randomness
Plants vs. Zombies 2: It's About Time leans a little harder on optimization, though the gap is small.
Jurassic World: The Game
Park economy and team composition are the real system
Plants vs. Zombies 2: It's About Time
Lawn economy and plant placement are the solvable core
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.
