This review is based on Pokemon: Let’s Go Eevee. I have not had hands-on time with Pokemon: Let’s Go Pikachu.
Pokemon: Let’s Go is the newest mainline game in the Pokemon series. It is a reimagining of the 1st Generation games set in the Kanto region. The series started with Pokemon Red/Blue when it was released internationally (originally Pokemon Red/Green/Blue were Japan-only releases, though Red/Green would eventually be released on the Virtual Console in 2016). The game combines elements of the original Red/Blue with the companion Pokemon plotline of Yellow (where Pikachu loved you so much at first sight, he refused to stay in a pokeball and walked with you instead) and the catching mechanics of Pokemon Go. It’s a lot to take in.
