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

Optimization · Pure Optimization
An auto-battling deckbuilder about building a loop to defeat the Lich.

Optimization · Pure Optimization
Ambitious X-COM entry defending a single city with real-time tactical combat.
Loop Hero leans Optimization (Pure Optimization); X-COM: Apocalypse 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.
Loop Hero
Autobattler, almost no inputs.
X-COM: Apocalypse
Optional real-time mode adds slight dexterity.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Loop Hero
Enemies follow scripts.
X-COM: Apocalypse
Alien behavior is systematic, not adaptive.
X-COM: Apocalypse leans a little harder on variance, though the gap is small.
Loop Hero
Card draws and loot drops randomize.
X-COM: Apocalypse
Hidden enemies and random raids drive uncertainty.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Loop Hero
Deck and tile placement reward deep optimization.
X-COM: Apocalypse
City politics, economy and tech routing decide the war.
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.
