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
A gothic horror FPS where a paranormal investigator fights a family curse with revolver in one hand and spells in the other.

Execution · Practiced Mastery
A top-down shooter testing aim and ammo management while rescuing victims.
Clive Barker's Undying leans Execution (Practiced Mastery); Ghoul Patrol 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.
Clive Barker's Undying
Dual-wielding spells and guns under pressure
Ghoul Patrol
Aiming and dodging enemies under ammo pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Clive Barker's Undying
Horrors follow scripted patterns despite feeling malevolent
Ghoul Patrol
Enemies follow scripted patterns, no adaptation
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Clive Barker's Undying
First-run scares and unknown manor secrets hide information
Ghoul Patrol
Some spawn and item randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Clive Barker's Undying
Spell upgrades and Scrye-revealed puzzles reward system mastery
Ghoul Patrol
Managing limited ammo and rescue routing matters
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.
