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

Optimization · Pure Optimization
A small-plot city builder where specialization economics and traffic engineering decide success.

Optimization · Pure Optimization
Scheduling scarce time and resources across a base run by copies of yourself.
SimCity (2013) leans Optimization (Pure Optimization); The Alters leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
SimCity (2013)
Mouse planning; no dexterity demands.
The Alters
Third-person walking and menus, no twitch demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
SimCity (2013)
No opponent; multiplayer regions cooperate.
The Alters
No adaptive opponent, only systems and story beats
The Alters leans a little harder on variance, though the gap is small.
SimCity (2013)
Agent simulation quirks behave unpredictably.
The Alters
Unscouted events and alter reactions surprise first runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
SimCity (2013)
Specialization chains and traffic layouts reward systematic planning.
The Alters
Time, resource and crew scheduling under deadlines is the 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.
