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 · Systems & Chaos
A cosy-eldritch fishing game about hauling secrets from dark water.

Optimization · Pure Optimization
A story-driven survival adventure alone on a hostile alien planet.
DREDGE leans Optimization (Systems & Chaos); The Solus Project 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.
DREDGE
Fishing minigames and night dodging, light demands
The Solus Project
Exploration platforming with mild precision needs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
DREDGE
Horrors follow fixed rules
The Solus Project
No adaptive entities, only environment
DREDGE leans a little harder on variance, though the gap is small.
DREDGE
Fish spawns and fog-of-dread unknowns until mapped
The Solus Project
Alien caves hidden until explored, single playthrough mostly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DREDGE
Cargo tetris, routes, and upgrades reward planning
The Solus Project
Managing temperature, hunger, and route planning drives survival
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.
