Well I can't say this didn't exceed my expectations. I'm excited for the more casual things, such as walking with my Pokémon, and putting clothes of them. More of the cutesy stuff, I guess. I'm not all excited about the Pokémon selection, story, or region. Even though Gen I was what built Pokémon into what it is today, it's still far from the best (which is subjective of course, but oh well).
But I have my concerns, almost completely surrounding the sync and adaptations with/from Pokémon GO. I have so many questions about how this will work. Then there's the whole "Kanto only" clause to porting Pokémon between the games. Whether or not that includes Alolan forms effects whether or not I waste the summer away playing Pokémon GO or not, and could very well effect my decision on when to buy a Switch (and this game, by extension).
There's also this that is a tell-tale sign that this is a spin-off game, and isn't a part of Gen VIII:
Update #5: There are no online features for the games. Again, it’s for casual fans.
By that extension it's not Generation VII or VIII, it's just it's own thing. A completely unique spin-off game that has no relationships to any of the core games. Honestly, if they continued to make remakes like this I wouldn't be mad. But this also means this game isn't going to take over the meta. Ever. Meaning USUM still rules that for another year, until it's finally passed on to whatever awaits us in 2019.
How in TCG?
Will these sets in related to this game still under SM era? I think it is. Since it isn't a Gen 8 game.
This is how they'll have time to bring in Unova and Kanto sets before the Generation officially ends. Then they'll have some sort of Legendary Treasures-esque set and we'll move on to Generation VIII.
