head to head
Neither is simply harder - they are hard in different places. Democracy 4 demands more variance; Portal 2 demands more execution.

Optimization · Pure Optimization
Solving an interlocking policy simulation to stay elected - nearly pure systems play.

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
Democracy 4 leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Portal 2 leans clearly harder on execution.
Democracy 4
Clicking policy sliders involves zero physical skill
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.
Democracy 4
Voter blocs react by fixed simulation rules, not adaptation
Portal 2
No opponent; puzzles are static.
Democracy 4 leans clearly harder on variance.
Democracy 4
Random events and hidden voter thresholds inject mild uncertainty
Portal 2
Puzzles are deterministic with no randomness.
Portal 2 leans a little harder on optimization, though the gap is small.
Democracy 4
A perfect coach solves the policy-web economy almost entirely
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.
