Pokemon director, producer, and composer Junichi Masuda shared new details about Pokemon Let’s Go Pikachu and Let’s Go Eevee during Nintendo’s Treehouse Live stream today at E3 2018.
Capturing a Pokemon will earn you experience that will be distributed across your entire party. The relative size of the Pokemon you capture will determine the amount of experience you get. The larger the Pokemon, the more experience your party will receive. Additionally, Pokemon in the wild will be surrounded by an aura to indicate their size, with red indicating a larger than normal creature and blue indicating the Pokemon is smaller than average.
Masuda also revealed that your partner Pokemon, which follows you outside its Poke Ball as you traverse the world, will wag its tail when an item is nearby.
