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
A minimalist side-scrolling strategy where a mounted monarch drops coins to build walls against nightly greed raids.

Optimization · Pure Optimization
A farm-life sim solved by season routing and profit optimization.
Kingdom: New Lands leans Optimization (Pure Optimization); Stardew Valley leans Optimization (Pure Optimization).
Kingdom: New Lands leans a little harder on execution, though the gap is small.
Kingdom: New Lands
Just riding and coin-dropping under time pressure
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.
Kingdom: New Lands
Greed waves follow deterministic escalation
Stardew Valley
No adaptive opponent exists
Kingdom: New Lands leans a little harder on variance, though the gap is small.
Kingdom: New Lands
Island layouts and vendor spawns randomise
Stardew Valley
Crop luck and geode RNG matter modestly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Kingdom: New Lands
Expansion order and economy timing decide survival
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.
