PERMANENT UNLOCKS
Meta-progression that survives death — new items entering the drop pool, characters and starting options unlocking, permanent stat purchases — accumulating across runs in games built on losing.

Rogue Legacy branded the formula (spend each run's gold on permanent manor upgrades), Hades made it narrative-complete (death is the story's forward motion, mirror upgrades its mechanical floor), Slay the Spire and Monster Train unlock cards into future draft pools, and Dead Cells meters weapon unlocks through collected cells. Designers add permanent unlocks because pure roguelike loss economics filter for a narrow audience: when a failed run yields nothing, most players experience punishment, but when every run deposits something permanent, failure becomes investment — the run was lost, the war progresses — which converts the genre's brutal variance into a retention curve. Unlocks also solve complexity pacing: a full item pool overwhelms new players, so gating content behind unlocks doubles as a tutorialization schedule, revealing depth at the rate players earn it. Key decisions: power unlocks versus option unlocks (permanent stat gains eventually trivialize the game — the Rogue Legacy critique; new items and characters add variety without inflating the floor), unlock pacing against expected run counts, and whether unlocks dilute the pool with duds (every unlocked card changes future draft odds — sometimes for the worse, a genuinely interesting cost). Pitfall: difficulty designed around completed meta-progression — when the base game is tuned for a maxed mirror, early runs aren't hard, they're unfinished, and players correctly perceive that they're grinding to reach the game's actual starting line.
