If we were able to stay at the Pokemon league after becoming the champion and take challengers as the champion would be so fun. Or be able to be a gym leader. That is the dream for post game content. Or a you can become like a real pokemkn contest star, a Pokemon center helper, a gym leader, a breader... Like actual jobs once your done and get rewards for it
I'm finally finishing Heart Gold. I forgot about my Spike Eared Pichu Gizamimi! I played through this game with a Jirachi on my team as well lol. Headed to slay Blaine now.
