Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
A tower-defense game about building optimal mazes and tower combinations.
RollerCoaster Tycoon 2 leans Optimization (Pure Optimization); Super Sanctum TD 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.
RollerCoaster Tycoon 2
Track building is grid-based with modest placement precision demands
Super Sanctum TD
