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 · Mind & Math
A nuclear strategy game testing cold optimization and the timing of betrayal.

Optimization · Mind & Math
Console-first RTS translating Halo's factions into streamlined base-and-army battles.
DEFCON leans Optimization (Mind & Math); Halo Wars leans Optimization (Mind & Math).
Halo Wars leans a little harder on execution, though the gap is small.
DEFCON
Issuing orders needs no dexterity, only attention
Halo Wars
Controller macro is deliberately light
DEFCON leans a little harder on reads, though the gap is small.
DEFCON
Timing betrayals and first strikes against humans is the heart
Halo Wars
Versus humans, build choices are mindgames
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
DEFCON
Hidden submarine and fleet positions reward scouting
Halo Wars
Scouting hides enemy composition early
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
DEFCON
Launch timing, placement and alliance math are deeply solvable
Halo Wars
Build orders and counter-unit economy
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.
