>>47566890You can start with FRLG to refamiliarize yourself with the series in a familiar region, then go to Emerald, HGSS, Platinum, BW, BW2 in that order. XY...exists and it's kind of shit, but it's a new region that you might want the experience of going through if you still like the series up until that point. USUM is a lot better than XY and worth playing either way if you can emulate 3DS games. Don't bother with LGPE or SWSHit.
You can skip FRLG if you feel you remember enough about Yellow, and ORAS is a new take on Hoenn that should only be played after Emerald regardless.
