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

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

Optimization · Pure Optimization
The 2001 Civilization entry that introduced culture, strategic resources and refined empire micromanagement.
Loop Hero leans Optimization (Pure Optimization); Sid Meier's Civilization III leans Optimization (Pure Optimization).
Loop Hero leans a little harder on execution, though the gap is small.
Loop Hero
Autobattler, almost no inputs.
Sid Meier's Civilization III
No dexterity in a turn-based interface
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.
Sid Meier's Civilization III
AI personalities are fixed and mappable
Loop Hero leans a little harder on variance, though the gap is small.
Loop Hero
Card draws and loot drops randomize.
Sid Meier's Civilization III
Random maps, resources and combat rolls matter early
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.
Sid Meier's Civilization III
Corruption math, worker turns and culture borders reward deep optimization
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.
