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.

Execution · Practiced Mastery
Zelda-meets-God-of-War action adventure starring the horseman War.

Execution · Practiced Mastery
A Platinum-made cel-shaded brawler where the Autobots fight Megatron with stylish combo combat.
Darksiders leans Execution (Practiced Mastery); Transformers: Devastation leans Execution (Practiced Mastery).
Transformers: Devastation leans a little harder on execution, though the gap is small.
Darksiders
combo-driven combat with dodge timing
Transformers: Devastation
Platinum dodge-offset timing drives the combat
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Darksiders
enemies are scripted
Transformers: Devastation
Decepticons run learnable scripted patterns
Transformers: Devastation leans a little harder on variance, though the gap is small.
Darksiders
world and bosses are fixed
Transformers: Devastation
Random weapon drops shape loadouts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Darksiders
Zelda-style dungeons and upgrade routing
Transformers: Devastation
Weapon synthesis, ability builds, boss moveset 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.
