Ask for the shape of the challenge.

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

Hundreds of hours of interlocking systems with a mid-game crisis on a timer. Most losses happen fifty in-game years before anybody notices them.

Every puzzle teaches a rule it refuses to state, and the island is perfectly happy to let you stand in front of a panel you have no vocabulary for yet.

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.

The rare strategy game that is also an execution test: the plan is worthless if your hands cannot run it at the pace it assumes. The campaign is a gentle front for that.

A MOBA played from behind the character, so half your abilities have to be aimed and the other half have to be aimed while something is aiming at you.

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 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.
