How it works
Objective
Guide your dynasty across generations (867-1453 CE) — expand realm, cultivate heirs, deal with intrigue, survive succession crises, potentially claim greatness.
Rules
Basic rules
PLAY A CHARACTER — not a nation. You die → play your heir. If dynasty dies out = game over
Signature character-based (not nation-based) design.
CHARACTER TRAITS: physical + personality + genetic + lifestyle traits shape decisions + relationships

LIFESTYLE FOCUS: 5 lifestyles (Diplomacy, Martial, Stewardship, Intrigue, Learning) each with 3 focus trees → 30+ perk trees
Signature lifestyle system.
STRESS + MENTAL HEALTH — traits opposed by actions accumulate stress; enough stress = mental breakdown giving penalties/negative traits
Signature stress/mental system.
SUCCESSION LAWS: primogeniture, elective, partition, tanistry, seniority — enormous strategic weight
Signature succession complexity.
FAITH + CULTURE: fully customisable Faith Doctrines + Cultural Traditions with tenets + heresies
Signature faith/culture editor.
