Pokmon games, much like the anime that got all of us into them, arent exactly straight lines with beginnings and endings. Yeah, you start your adventure, catch some Pokmon, defeat the evil team, beat the Elite Four, etcetera, but actually becoming a Pokmon Master? Becoming the best there ever was? That takes more than just one adventure. This is why many Pokmon games, both in and out of the mainline titles, have some manner of post-game to really test your mettle.
