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
A city builder where your whole town flies, forcing constant trade-offs between weight, lift and resources.

Optimization · Pure Optimization
LucasArts adventure sending Indy down three routes toward Atlantis.
Airborne Kingdom leans Optimization (Pure Optimization); Indiana Jones and the Fate of Atlantis 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.
Airborne Kingdom
Gentle steering of the city; minimal dexterity.
Indiana Jones and the Fate of Atlantis
Pointing and clicking, light fistfight option
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Airborne Kingdom
No adversaries; ground towns offer fixed quests.
Indiana Jones and the Fate of Atlantis
No adaptive opposition
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Airborne Kingdom
Resource spread across the procedural map varies mildly.
Indiana Jones and the Fate of Atlantis
Solutions hidden until reasoned out
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Airborne Kingdom
Balancing lift, weight, fuel and layout is the core puzzle.
Indiana Jones and the Fate of Atlantis
Three-path puzzle chains reward deduction
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.
