head to head
Neither is simply harder - they are hard in different places. Life is Feudal: Forest Village demands more variance; Portal 2 demands more execution.

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

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
Life is Feudal: Forest Village leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Portal 2 leans clearly harder on execution.
Life is Feudal: Forest Village
Pause-friendly city building has no twitch demands
Portal 2
Portal placement requires some precision but timing is lenient.
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 2
No opponent; puzzles are static.
Life is Feudal: Forest Village leans clearly harder on variance.
Life is Feudal: Forest Village
Weather and harvest swings add survival noise
Portal 2
Puzzles are deterministic with no randomness.
Portal 2 leans clearly harder on optimization.
Life is Feudal: Forest Village
Food chains, labor allocation and expansion timing decide survival
Portal 2
Solving the puzzle's logic IS the entire 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.
