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
The 1992 template for the entire real-time strategy genre.

Optimization · Pure Optimization
Deadline-driven strategy where three explorers split duties harvesting fruit with Pikmin squads.
Dune II leans Optimization (Pure Optimization); Pikmin 3 leans Optimization (Pure Optimization).
Pikmin 3 leans a little harder on execution, though the gap is small.
Dune II
Slow clicking, no precision demands
Pikmin 3
Juggling three captains needs deft control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dune II
AI attacks on predictable timers
Pikmin 3
Wildlife behavior is fixed
Dune II leans a little harder on variance, though the gap is small.
Dune II
Unscouted map and spice fields early
Pikmin 3
Fruit and enemy placements are static
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dune II
Build orders and base economy decide everything
Pikmin 3
Multi-captain routing and fruit-deadline planning dominate
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.
