head to head
Starbound asks more than The Elder Scrolls V: Skyrim, and the gap is variance.

Optimization · Pure Optimization
A 2D sandbox of procedurally generated planets driven by crafting progression.

Optimization · Pure Optimization
An open-world RPG mostly about discovering and stacking exploitable progression systems.
Starbound leans Optimization (Pure Optimization); The Elder Scrolls V: Skyrim 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.
Starbound
Light platforming and combat, generous margins
The Elder Scrolls V: Skyrim
Combat is forgiving; aim and timing rarely punish you.
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
The Elder Scrolls V: Skyrim
Enemy AI is scripted and exploitable; not adaptive.
Starbound leans clearly harder on variance.
Starbound
Procedural planets and loot keep early exploration unknown
The Elder Scrolls V: Skyrim
Loot tables and leveled lists inject mild randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Starbound
Gear tiers, farming, and progression routes dominate
The Elder Scrolls V: Skyrim
Skill stacking, enchant loops, and exploits are deeply solvable.
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.
