Meta-Progression

Meta-progression is advancement that outlives the attempt which earned it. A run ends in death, the run-scoped state is discarded, and something — a currency, an unlocked option, a permanent statistical increase — persists into the next one. It is the single mechanism that separates the roguelite from the Roguelike proper, whose older definition insists that death returns the player to genuine zero.

The design problem it solves is the tail of the failure curve. A run-based game asks the player to lose repeatedly, and pure Seeded Randomness guarantees that some losses will be attributable to the seed rather than the player. Persistent unlocks convert those losses into deposits: the attempt still failed, but it was not spent. Hades is the case usually cited because it also spends the currency on narrative, so the payment for a failed run is a scene rather than a number, and the game's most-repeated activity becomes its primary delivery mechanism for story rather than an interruption of it.

The mechanism is also the genre's main failure mode. Persistent power makes early runs measurably harder than late ones, which inverts the difficulty curve against the player's growing skill. Push it far enough and the honest description of a loss changes from "played badly" to "attempted too early" — the game has begun measuring grind and calling it skill, a clean instance of Goodhart's Law operating on the player's own sense of progress. The extractive end of this design space is continuous with Gacha Monetization, where the persistent track is deliberately paced to be uncomfortable and the discomfort is for sale, and with the compulsion literature that Physical Dependence describes in a different register.

The line worth holding is whether persistence removes obstacles or removes decisions. An unlock that adds a viable strategy widens the space the player reasons about; a flat damage increase narrows it, since the same strategy simply works now. The first sustains the Game Feel of mastery over hundreds of runs, and the second replaces mastery with attendance — which is why the mechanic appears wherever a designer wants a hard game to become a daily one, including in Live Service Game design that is not run-based at all.
