head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Mind & Math
Console-first RTS translating Halo's factions into streamlined base-and-army battles.

Optimization · Mind & Math
Trajectory math and arsenal economy against humans under random wind.
Halo Wars leans Optimization (Mind & Math); Scorched Earth leans Optimization (Mind & Math).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Halo Wars
Controller macro is deliberately light
Scorched Earth
Dialing angle and power is deliberate, not twitch
Halo Wars leans a little harder on reads, though the gap is small.
Halo Wars
Versus humans, build choices are mindgames
Scorched Earth
Hot-seat humans reward predicting their targets and buys
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Halo Wars
Scouting hides enemy composition early
Scorched Earth
Random terrain and wind perturb every shot
Halo Wars leans a little harder on optimization, though the gap is small.
Halo Wars
Build orders and counter-unit economy
Scorched Earth
Trajectory math and weapon economy decide who survives
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.
