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.

Execution · Practiced Mastery
An arcade FPS that scores you for killing enemies in the most creative ways possible.

Execution · Practiced Mastery
A customizable Jedi action game centered on deep lightsaber combat.
Bulletstorm leans Execution (Practiced Mastery); Star Wars Jedi Knight: Jedi Academy 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.
Bulletstorm
Leash, kick, and shot timing drive skillshot chains
Star Wars Jedi Knight: Jedi Academy
Saber acrobatics and timing dominate combat
Star Wars Jedi Knight: Jedi Academy leans a little harder on reads, though the gap is small.
Bulletstorm
Enemies are scripted fodder for your combos
Star Wars Jedi Knight: Jedi Academy
Long-lived MP dueling scene adds human mindgames
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bulletstorm
Arenas and spawns are fixed and learnable
Star Wars Jedi Knight: Jedi Academy
Mission order choice, otherwise fixed content
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bulletstorm
Maximising skillshot score per arena is a solvable puzzle
Star Wars Jedi Knight: Jedi Academy
Saber styles and Force builds reward mastery
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.
