>>23423092FRLG, then HGSS. Then after that, it'll be split between Emerald and ORAS. But personally, I'd suggest ORAS because most of the people saying Emerald are just butthurt Frontier babies but take your pick. Then Platinum, if you want you can play BW otherwise just go straight to BW2. Then XY. They're all worth playing, none of them really stand out as bad (though I can't say how good BW were since I only played Black 2) and they all collectively make the ultimate experience.
