head to head
Neither is simply harder - they are hard in different places. Life is Feudal: Forest Village demands more variance; Portal demands more execution.

Optimization · Pure Optimization
Balancing food chains and labor against seasonal attrition - a solvable settlement equation.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Life is Feudal: Forest Village leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Portal leans clearly harder on execution.
Life is Feudal: Forest Village
Pause-friendly city building has no twitch demands
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.
Life is Feudal: Forest Village
No adversary - just systems and seasons
Portal
No adversary modeling player.
Life is Feudal: Forest Village leans clearly harder on variance.
Life is Feudal: Forest Village
Weather and harvest swings add survival noise
Portal
Deterministic chambers; no randomness.
Portal leans a little harder on optimization, though the gap is small.
Life is Feudal: Forest Village
Food chains, labor allocation and expansion timing decide survival
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.
