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.

Variance · Systems & Chaos
A gothic exploration roguelike about sailing an underground ocean, trading terror for stories and profit.

Variance · Systems & Chaos
A 1-bit Junji Ito-styled roguelite where you solve randomized cosmic-horror mysteries.
Sunless Sea leans Variance (Systems & Chaos); World of Horror leans Variance (Systems & Chaos).
Sunless Sea leans a little harder on execution, though the gap is small.
Sunless Sea
Slow boat combat barely tests the hands
World of Horror
Turn-based menus; hands are irrelevant
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sunless Sea
Horrors are scripted or random, never adaptive
World of Horror
Eldritch events are random tables, not adaptive minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Sunless Sea
Hidden map, random events and unknown story branches dominate
World of Horror
Random mysteries, events, and curses dominate each run
World of Horror leans a little harder on optimization, though the gap is small.
Sunless Sea
Trade routes and fuel math converge once mapped
World of Horror
Stat economy and event knowledge converge to strong play
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.
