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

Optimization · Pure Optimization
Team building and type-matchup optimization through a scripted island campaign.

Optimization · Systems & Chaos
A physics sandbox where you place wobbly armies and watch ragdoll battles resolve themselves.
Pokémon Moon leans Optimization (Pure Optimization); Totally Accurate Battle Simulator leans Optimization (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Moon
Turn-based menus require no dexterity
Totally Accurate Battle Simulator
Place units then watch; no hands required
Pokémon Moon leans a little harder on reads, though the gap is small.
Pokémon Moon
Scripted trials and trainers; competitive play is a niche mode
Totally Accurate Battle Simulator
No adaptive opponent in campaign sandbox
Totally Accurate Battle Simulator leans a little harder on variance, though the gap is small.
Pokémon Moon
Encounter tables, catch rolls and crits are mappable RNG
Totally Accurate Battle Simulator
Wobbly physics makes identical setups resolve differently
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Moon
Team composition and type math are the solvable core
Totally Accurate Battle Simulator
Unit counters and placement solve each scenario
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.
