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 2D sandbox of procedurally generated planets driven by crafting progression.

Optimization · Systems & Chaos
A pixel-horror adventure about hunting a witch inside a nightmarish corporation.
Starbound leans Optimization (Pure Optimization); Yuppie Psycho leans Optimization (Systems & Chaos).
Starbound leans a little harder on execution, though the gap is small.
Starbound
Light platforming and combat, generous margins
Yuppie Psycho
Light stealth and chase sequences
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Starbound
Procedural NPCs follow simple fixed behaviours
Yuppie Psycho
Office horrors are scripted, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Starbound
Procedural planets and loot keep early exploration unknown
Yuppie Psycho
Unknown scripted events dominate a blind playthrough
Starbound leans a little harder on optimization, though the gap is small.
Starbound
Gear tiers, farming, and progression routes dominate
Yuppie Psycho
Puzzle solutions and item routing are fixed
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.
