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
Turn-based infiltration puzzles with fully solvable deterministic solutions.

Optimization · Pure Optimization
A life simulator where planning schedules and needs against a solvable system is the real game.
Deus Ex GO 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.
Deus Ex GO
Turn-based taps, no dexterity at all
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.
Deus Ex GO
Guards move by fixed deterministic rules
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.
Deus Ex GO
Puzzle states are fully visible from the start
The Sims 4
minor random events and needs decay
Deus Ex GO leans a little harder on optimization, though the gap is small.
Deus Ex GO
Each board is a literally solvable movement puzzle
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.
