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 · Practiced Mastery
Action RPG prequel to FFVII whose combat spins a slot machine for buffs.

Execution · Practiced Mastery
Pixel roguelite dungeon crawler where persistent town upgrades fuel ever-deeper runs.
Crisis Core: Final Fantasy VII leans Optimization (Practiced Mastery); Heroes of Hammerwatch leans Execution (Practiced Mastery).
Heroes of Hammerwatch leans a little harder on execution, though the gap is small.
Crisis Core: Final Fantasy VII
real-time dodging and attack timing
Heroes of Hammerwatch
Kiting dense mobs and dodging projectiles
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crisis Core: Final Fantasy VII
no adaptive opponent
Heroes of Hammerwatch
Enemies are non-adaptive swarms
Heroes of Hammerwatch leans a little harder on variance, though the gap is small.
Crisis Core: Final Fantasy VII
DMW slot reels randomize limit breaks and levels
Heroes of Hammerwatch
Procedural floors and item drops
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crisis Core: Final Fantasy VII
materia fusion is a deep solvable system
Heroes of Hammerwatch
Town upgrades, class builds, and meta progression
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.
