 ## Checklist
-- [ ] Define Game type (id, name, generation, region, routes)
-- [ ] Define Route/Area type (id, name, available Pokémon, game)
-- [ ] Define Pokemon type (national dex number, name, types, sprite URL)
-- [ ] Define Encounter type (route, pokemon, nickname, status, caught date)
-- [ ] Define NuzlockeRun type (game, settings, encounters, start date)
-- [ ] Define RuleSettings type (hardcore mode, level caps, duplicates clause, etc.)
+- [x] Define Game type (id, name, slug, generation, region, boxArtUrl, releaseYear)
+- [x] Define Route/Area type (id, name, gameId, order)
+- [x] Define Pokemon type (id, nationalDex, name, types, spriteUrl)
+- [x] Define Encounter type (id, runId, routeId, pokemonId, nickname, status, catchLevel, faintLevel, caughtAt)
+- [x] Define NuzlockeRun type (id, gameId, name, status, rules, startedAt, completedAt)
+- [x] Define RuleSettings type (already existed in rules.ts)
+- [x] Define RouteEncounter type (id, routeId, pokemonId, encounterMethod, encounterRate)
+- [x] Define EncounterStatus and RunStatus discriminated union types
 
 ## Notes
 - Keep types flexible for future expansion
