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
Beloved sequel layering invention, photography, and town-building onto dungeon runs.

Optimization · Pure Optimization
A 2D sandbox of procedurally generated planets driven by crafting progression.
Dark Cloud 2 leans Optimization (Pure Optimization); Starbound leans Optimization (Pure Optimization).
Dark Cloud 2 leans a little harder on execution, though the gap is small.
Dark Cloud 2
dodge-and-strike combat plus photo hunting
Starbound
Light platforming and combat, generous margins
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Cloud 2
no adaptive opponent
Starbound
Procedural NPCs follow simple fixed behaviours
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Cloud 2
procedural dungeons and invention drops
Starbound
Procedural planets and loot keep early exploration unknown
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dark Cloud 2
weapon synthesis and Georama building run deep
Starbound
Gear tiers, farming, and progression routes dominate
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.
