Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
Classic inventory-puzzle deduction through a fixed comedic story.

Optimization · Pure Optimization
A life simulator where planning schedules and needs against a solvable system is the real game.
Runaway 3: A Twist of Fate leans Optimization (Pure Optimization); The Sims 4 leans Optimization (Pure Optimization).
The Sims 4 leans a little harder on execution, though the gap is small.
Runaway 3: A Twist of Fate
Pointing and clicking is the only physical act
The Sims 4

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

Runaway 3: A Twist of Fate leans a little harder on variance, though the gap is small.
