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

Execution · Practiced Mastery
Moody Halo side story about ordinary troopers piecing together a night in New Mombasa.

Execution · Practiced Mastery
A Star Wars shooter that adds lightsabers and Force-power progression.
Halo 3: ODST leans Execution (Practiced Mastery); Star Wars Jedi Knight: Dark Forces II leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Halo 3: ODST
Squishier soldier demands careful aim and positioning
Star Wars Jedi Knight: Dark Forces II
Saber timing and platforming over huge levels
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Halo 3: ODST
Covenant patrols are scripted, not adaptive
Star Wars Jedi Knight: Dark Forces II
Multiplayer duels existed; campaign AI is scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Halo 3: ODST
Open Mombasa hides clues until found
Star Wars Jedi Knight: Dark Forces II
Sprawling levels surprise once then map out
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Halo 3: ODST
Firefight wave knowledge and route planning
Star Wars Jedi Knight: Dark Forces II
Force power allocation and routing reward planning
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.
