head to head
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
Solving fixed light-and-shadow coordination puzzles at a forgiving narrative pace.

Optimization · Pure Optimization
A life simulator where planning schedules and needs against a solvable system is the real game.
Shady Part of Me leans Optimization (Pure Optimization); The Sims 4 leans Optimization (Pure Optimization).
Shady Part of Me leans a little harder on execution, though the gap is small.
Shady Part of Me
Gentle platforming with rewind removes any twitch pressure
The Sims 4
no physical skill ceiling at all
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Shady Part of Me
No opponent - a solo narrative puzzle journey
The Sims 4
no opponents, simulated NPCs only
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Shady Part of Me
Puzzles are fixed and fully visible once reached
The Sims 4
minor random events and needs decay
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Shady Part of Me
Coordinating girl and shadow through light logic is the game
The Sims 4
life and career system optimization dominant
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.
