An elevator system is not just a lift moving between floors. The interesting design problem is deciding which car should answer a request and how each car should order its stops without mixing building-level scheduling with elevator-level movement.
A library system becomes interesting the moment three copies of the same book exist. Learn how to model titles, physical copies, loans and reservations without putting every responsibility into one class.
Tic-Tac-Toe becomes an interesting LLD problem when the board size changes, rules evolve, invalid moves appear and the game engine must remain maintainable.
