head to head
Fat Princess asks more than Dune 2000, and the gap is reads.

Optimization · Practiced Mastery
Spice economy management and build-order knowledge with modest micro demands.

Optimization · Mind & Math
Team objective tug-of-war testing class economy and reading the other team's pushes.
Dune 2000 leans Optimization (Practiced Mastery); Fat Princess leans Optimization (Mind & Math).
Dune 2000 leans a little harder on execution, though the gap is small.
Dune 2000
Unit micro and build speed matter at competitive pace
Fat Princess
Simple hack-and-slash actions per class
Fat Princess leans clearly harder on reads.
Dune 2000
Human skirmishes add some build-order mind games
Fat Princess
Predicting enemy team pushes and rescues is constant
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dune 2000
Fog of war hides enemy composition until scouted
Fat Princess
Minor spawn and map noise
Dune 2000 leans a little harder on optimization, though the gap is small.
Dune 2000
Spice economy and build orders decide most games
Fat Princess
Class economy, cake feeding and upgrade timing win matches
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.
