>>46483642>Gen 1This is the only time it comes down solely to preference, Red, Blue, and Yellow are all viable options based on preference. Yellow has lots of nice little selection and encounter twists to match the anime but has no smoking gun to set it above the other options. FRLG also comes down to preference. Ignore Lets GO as they're really not giving the same offering as a mainline 2D game despite using one as the framework.
>Gen 2Crystal if you wanna play the GB versions, HGSS comes down to personal preference on each games Pokemon availability
>Gen 3Emerald. Pass on the remakes.
>Gen 4Platinum. Probably also pass on the remakes but we shall see.
>Gen 5Black or White based on preference of Pokemon availability. HIGHLY recommended to play the same version for 2 as the story will match up with 1 that way. So you'll probably want to scope out the options in 1 AND 2 before starting on 1.
>Gen 6 Pass.
>Gen 7Pass.
Gen 8
Pass.
