UNLOCKING NEW OPTIONS
The strategic layer's expanding menu — new buildings appearing after prerequisites, mission types unlocked by story progress, expanded policy choices as institutions grow, the command that wasn't there last month.

Distinct from ability unlocks (new player verbs) and unlock tiers (staged content ladders), this is option-space growth at the decision layer: XCOM's council missions and facility list expand as the campaign develops (the strategic game at month four offers choices month one couldn't imagine), 4X tech trees exist mostly to do this (each research is really a menu expansion — new units, buildings, and diplomatic options appearing in lists), Crusader Kings' lifestyle and dynasty systems open decision categories over generations, and roguelite campaign layers (Hades' contractor, Slay the Spire's unlocked events) grow the between-run option set. Designers grow option spaces gradually because full menus overwhelm and flat menus bore: presenting every choice from hour one buries the important ones in the possible ones (analysis paralysis is a count problem), while gradual expansion keeps each session's decision set fresh — the new option is attention-grabbing precisely because the menu was stable yesterday — and creates a second-order strategy layer, since unlocking itself becomes a choice (which branch of options do you open first — the expansion path is a build). Option growth also paces the fantasy of institutional development: organizations feel like they're maturing when their capabilities visibly compound (the resistance cell that once chose between two raids now coordinates a theater), and the expanding menu is that maturation made tangible. Key decisions: unlock drivers (research, story beats, resources, achievements — what earns new options defines what the game rewards), reversibility and exclusivity (options that lock alternatives make expansion a commitment; pure addition makes it accumulation), discoverability of the option-space's shape (visible locked options are goals; hidden ones are surprises — showing the silhouette of what could be unlocked converts the menu into a map), and option retirement — pruning obsolete choices as better ones arrive keeps menus decisive rather than archaeological. Pitfall: expansion as dilution — when new options are strictly-better replacements or situational clutter, the growing menu adds scrolling rather than strategy, and veterans navigate by ignoring nine-tenths of it; every added option should either open a new strategy or reprice existing ones, because a menu that grows without deepening is just interface inflation on a schedule.
