-status: draft

-Write integration tests for the games and routes API endpoints in `backend/src/app/api/games.py`.
+Write integration tests for the games and routes API endpoints in backend/src/app/api/games.py.
+
+## Key behaviors to test
+
+- Game CRUD: create (201), list, get with routes, update, delete (204)
+- Slug uniqueness enforced at create and update (409)
+- 404 for missing games
+- 422 for invalid request bodies
+- Route operations require version_group_id on the game (need VersionGroup fixture via db_session)
+- list_game_routes only returns routes with encounters (or parents of routes with encounters)
+- Game detail (GET /{id}) returns all routes regardless
+- Route create, update, delete, reorder
 
 ## Checklist
 
-- [ ] Test CRUD operations for games (create, list, get, update, delete)
-- [ ] Test route management within a game (create, list, reorder, update, delete)
-- [ ] Test route encounter management (add/remove Pokemon to routes)
-- [ ] Test bulk import functionality
-- [ ] Test region grouping/filtering
-- [ ] Test error cases (404 for missing games, validation errors, duplicate handling)
-
-## Notes
-
-- Use the httpx AsyncClient fixture from the test infrastructure task
-- Each test should be independent — use fixtures to set up required data
-- Test both success and error response codes and bodies
