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 · Pure Optimization
An auto-attacker where picking the right weapon evolutions wins by itself.

Optimization · Pure Optimization
A text adventure testing puzzle deduction and mapping hidden dungeon logic.
Vampire Survivors leans Optimization (Pure Optimization); Zork III: The Dungeon Master leans Optimization (Pure Optimization).
Vampire Survivors leans a little harder on execution, though the gap is small.
Vampire Survivors
Movement is trivial; no aim or precision required.
Zork III: The Dungeon Master
Typing commands has no physical ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Vampire Survivors
Enemies follow fixed spawn scripts; no adaptive opponent.
Zork III: The Dungeon Master
No adaptive opponent anywhere in the dungeon
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Vampire Survivors
Level-up offerings and pickup drops are randomized.
Zork III: The Dungeon Master
Hidden rooms and timed events punish unmapped exploration
Vampire Survivors leans a little harder on optimization, though the gap is small.
Vampire Survivors
Evolution paths and weapon combinations fully solve the run.
Zork III: The Dungeon Master
Puzzle solutions and routing are fully solvable with knowledge
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.
