SKILL SPECIALIZATION
Units and characters deepening into narrow excellence — the sniper who only snipes, colonists with burning passions for single jobs, skill systems where advancing one track forecloses others.

RimWorld's passion flames make specialization emergent (the colonist who loves cooking becomes your cook because growth follows joy), Kenshi and Project Zomboid grind skills by use until bodies encode their histories, XCOM's classes lock soldiers into roles at first promotion, Jagged Alliance prices mercenaries by their specialties, and MMO holy trinities (tank/healer/DPS) are specialization as social contract. Designers push units toward specialties because generalists dissolve decisions: when everyone can do everything, deployment is interchangeable and rosters are headcount — but specialists make every mission a casting problem (who do you bring when you can't bring everyone?), create interdependence that binds squads into organisms (the sniper needs the spotter; the tank needs the healer — vulnerability is the glue), and give individual units identity through capability silhouette (this dwarf is the legendary mason; that one can't be trusted with soup). Specialization also compounds attachment arithmetic: a specialist's death subtracts something the roster can't replace by promotion, which is what makes loss systems bite. The acquisition path flavors everything — chosen specialization (pick the class) is player authorship, use-based growth (skills improve by doing) is biography, and passion-driven growth (RimWorld) is character. Key decisions: how hard the walls between specialties are (soft focus versus locked classes versus mutually exclusive mastery caps), cross-training costs and whether aging veterans can retrain, and depth-versus-need tension — the game must regularly need specialties it punishes you for lacking, or specialization is flavor text on a stat sheet. Pitfall: specialization without demand variety — if every mission needs the same three specialties, the roster converges and 'specialization' means everyone built identically; the system only generates decisions while the game keeps asking different questions, forcing depth in some skills to mean genuine absence in others.
