Axis by axis
Execution0 vs 1
Cities: Skylines II leans harder on execution: no mechanical demand
Reads0 vs 0
Even - both lean on reads about the same.
Variance1 vs 2
Cities: Skylines II leans harder on variance: minor sim noise
Optimization10 vs 9
Cities: Skylines leans harder on optimization: Traffic flow, zoning, and budgets are fully solvable.
Two games can score the same on an axis and still test it in very different ways - read each rationale, not just the number.
