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

Optimization · Pure Optimization
Procedural space exploration sandbox with crafting depth.

Optimization · Pure Optimization
A meditative physics puzzle about plotting efficient absorption paths while spending mass wisely.
No Man's Sky leans Optimization (Pure Optimization); Osmos 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.
No Man's Sky
Light shooter and flight inputs
Osmos
Gentle propulsion nudges need patience more than twitch precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
No Man's Sky
Mostly solo, sparse PvP
Osmos
Solo ambient drift - no adaptive opponent exists
No Man's Sky leans a little harder on variance, though the gap is small.
No Man's Sky
Procedural planets and loot
Osmos
Mote layouts vary slightly but physics are fully visible
No Man's Sky leans a little harder on optimization, though the gap is small.
No Man's Sky
Base, freighter, expedition progression
Osmos
Planning efficient absorption paths while conserving mass is the game
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.
