I mean I would like the all-encompassing Pokemon game with three or four or all regions and every pokemon and I want it in a style of a HD GBA game. I'm not asking for ray tracing open world here.
It would have to be a big sendoff project, and I'm not sure if GF has the guile to pull it off.
I could see it happening in three fashions:
1. Typical Pokémon game; new region that serves as the hub, and you play and fuck around there until you beat the champion and post-game is region exploration.
2. You pick a starter region and play through it like a regular game. Then, region exploration post.
3. (My expectation): GF takes the laziest route possible: All regions are available to play in, but only one region. GF hypes it up as a big "Your Region v. Other Region" deal. Throw it some notable trainer cameos, and voila!
Also, JFC. The Pokémon World is huge. We have eight regions, and I feel we've barely explored half of them. And canon or non-canon, take into consideration regions such as Fiore, Almia, Oblivia, Orre, and whatever I'm missing, there's so much surface to scratch, the itch is unbearable.
