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

Optimization · Pure Optimization
Tests demon-fusion team building and tactical grid optimization against scripted encounter design.

Optimization · Pure Optimization
A farm-life sim solved by season routing and profit optimization.
Shin Megami Tensei: Devil Survivor 2 - Record Breaker leans Optimization (Pure Optimization); Stardew Valley 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.
Shin Megami Tensei: Devil Survivor 2 - Record Breaker
Turn-based menus - hands are irrelevant
Stardew Valley
Trivial timing on fishing and combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Shin Megami Tensei: Devil Survivor 2 - Record Breaker
Enemy AI follows mappable priorities, never models you
Stardew Valley
No adaptive opponent exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Shin Megami Tensei: Devil Survivor 2 - Record Breaker
Demon auction and skill cracks add manageable RNG
Stardew Valley
Crop luck and geode RNG matter modestly
Shin Megami Tensei: Devil Survivor 2 - Record Breaker leans a little harder on optimization, though the gap is small.
Shin Megami Tensei: Devil Survivor 2 - Record Breaker
Team building, fusion and grid positioning are deeply solvable
Stardew Valley
Routing seasons, profit loops, and bundles dominates
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.
