Ask for the shape of the challenge.

A storyteller AI aims raids at whatever you are worst at, and mood is a second economy that collapses faster than the defensive one.

Thermodynamics as a colony sim. The base that runs beautifully for forty cycles fails on the sixtieth because the heat had nowhere to go.

Not difficult so much as undocumented — everything that kills you was perfectly legible, in a menu you did not know existed.

A hundred and seventy champions, each with four abilities you are expected to know the cooldowns of, and the tutorial covers none of it.

Every hero is free and every one of them can do something no other game would let a hero do, which is why the learning curve is measured in years rather than hours.

A simulated ecosystem that has no interest in being fair. Movement takes twenty hours to feel deliberate, the rain cycle takes back anything you did not bank, and nothing is explained at any point.

Every pixel is simulated, so every run is one wand mistake away from killing you instantly. Wand editing is a programming language the game never teaches.

Every wall, floor and ceiling is destructible and every one of seventy-odd operators changes what a room means, so the hardest part is a memory problem rather than an aiming one.

Souls difficulty plus a fighting game’s input list plus a loot game’s spreadsheet, and none of the three is optional.

Every death is your own fault and every run is a fresh cave. The systems interact thoroughly enough that it kills you in ways nobody has written down yet.
