>>54545169>XYLargest regional dex of any game in the series, more than twice as much as every prior game except GSC and BW2
The PSS is the best implementation of online features in the series and introduced cool shit like Wonder Trades
Super Training was the first real step toward making EVs and other competitive mechanics easily accessible to normal people
>LGPEIt's basically just Yellow combined with GO. I haven't played it, but I doubt it's entirely without value. It was also never really necessary to own or play so I wouldn't consider it on the same level as the other main series games, even if they say it technically counts as one.
>SwShI think these are probably the worst games, but they deserve some credit for introducing ideas like open-world design and raids that later games would do better.
>BDSPYou can get every single pre-Gen V Pokémon in these games. I think that's a pretty significant benefit over the original DPPt.
