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 · Pure Mechanics
A Sega arcade brawler where collecting orbs transforms you into beast forms.

Execution · Practiced Mastery
Gothic action platformer starring a one-eyed undead knight reclaiming his honor.
Altered Beast leans Execution (Pure Mechanics); MediEvil leans Execution (Practiced Mastery).
Altered Beast leans a little harder on execution, though the gap is small.
Altered Beast
Punch timing in a slow brawler
MediEvil
stiff swordplay and platforming timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Altered Beast
Enemies spawn on fixed scripts
MediEvil
skeletons follow fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Altered Beast
Power-up wolves always same spots
MediEvil
deterministic levels and secrets
MediEvil leans a little harder on optimization, though the gap is small.
Altered Beast
Short, memorisable stage routes
MediEvil
chalice hunting and weapon progression routing
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.
