>>51282247Postgame is kinda like the stereotypical end of the heroes journey, after defeating 'evil' the hero must return to find how the world changed and how he has changed. This like the case for the lord of the rings ending in the books where the hobbits go back to the shire to find what happened to it. In that sense post Game is going back to rediscover the world after the hero comes back home.

>Gen 1Though not as big as other games celurean cave is post game and it tests the player on all aspects.
