Pokémon Arceus

My favorite game is Pokemon Arceus. This game was the first game to be open world. The game takes place in Hisui region, where humans and Pokemon were not living in harmony. This Hisui region will be named Sinnoh region. With this game, the player becomes the member of Survey Corps of Galaxy Expedition team. He or she must do field research in certain places in Hisui region to complete the first Pokédex in this region. While investigating new Pokemon, players must deal with 5 Noble Pokemon. These Pokemon must be defeated by using balms and battling them. Also, players must complete research tasks for each Pokemon to complete Pokédex. Players can change clothes, buy items, change hair, take photos, and change Pokemon team in Jubilife Village. The only way to explore more places in Hisui region is earn  ranks from Captain Cyllene. Along the way, players discover what is Arceus and why.
