head to head
My Time at Sandrock asks more than Portal, and the gap is variance.

Optimization · Pure Optimization
Scheduling and production-chain planning in a workshop economy with light combat.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
My Time at Sandrock leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Portal leans a little harder on execution, though the gap is small.
My Time at Sandrock
Light action combat never gates progress seriously
Portal
Portal placement timing modest.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
My Time at Sandrock
Townsfolk and monsters run fixed routines
Portal
No adversary modeling player.
My Time at Sandrock leans clearly harder on variance.
My Time at Sandrock
Some gathering randomness, quickly mapped
Portal
Deterministic chambers; no randomness.
Portal leans a little harder on optimization, though the gap is small.
My Time at Sandrock
Workshop production chains, scheduling and commissions are the game
Portal
Pure puzzle-solving optimization.
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.
