Shadow of the Colossus. First time you climb that tutorial hill, you see it walking. It's massive. You run towards it, maybe fire an arrow. It slowly turns towards you. It starts moving towards you. It then raises its giant mace, and strikes down, shaking the ground and toppling you to the ground with the sheer force of its strength. After getting back up, you then run to its feet, trying not to get stomped on. You grab onto the back of its ankle, and stab it. It wobbles. You stab again. It falls. While its down you then climb its waist, then as it's getting up you climb up its back. Its up, you reach its neck. You hold on for dear life while it tries to shake you off. Birds are circling. You make your way to the top of its head, and stab. And stab. And stab.
It falls. It dies.
You just toppled a giant. Not through a quick time event, not through a cutscene, but by actually dodging its attacks, climbing it, and killing it.
