A crafting life-sim about running a workshop in a post-apocalyptic town.

Optimization · Pure Optimization

My Time at Portia leans Optimization (Pure Optimization); Pokémon Snap leans Optimization (Pure Optimization).
Pokémon Snap leans a little harder on execution, though the gap is small.

Light combat and crafting timing.
Pokémon Snap
Timing photos on a moving rail
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

My Time at Portia leans a little harder on variance, though the gap is small.
My Time at Portia
Loot and gifts vary.
Pokémon Snap
Minor behavioral wiggle per run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
My Time at Portia
Workshop scheduling and commissions reward optimization.
Pokémon Snap
Triggering rare poses is route knowledge
