I've wanted a 'silly epic fantasy' game for a while now, kinda like Roland the Barbarian where we take every stupid stereotype, amplify them a few times, and just mush them up together in a hilarious hotpot of "WTF is dis I don't even". And--- pokemon. Because why not? I'm thinking casual/high casual for this, because I don't really enjoy one-liners and people should know at that point how to help drive a story forward. Give the premise a quick read if you're interested:
"The high priestess of Arceus committed the ultimate betrayal. The age of Zygarde was coming to a close and the age of Arcticuno was once again drawing near, marking the dawn of a new millennium that would be passed down through the influences of the legendaries until the age of Zygarde once again ended and the process would repeat itself. All over the world, from the viking barbarians of Johtoheim to the ninjas of Sinnohbi, from the pointy-eared-hippies of Middle Hoenn to the regal politicians of the Kollussus Empire, people put down their weapons and their agendas in a rare window of peace. They prepared for the biggest celebration this side of a thousand years - but when the new age begun and the fireworks exploded on the skies above, the voices that had harbored only song and laughter turned to hysteric screams. Wild pokemon lost their senses and all their compassion, becoming mindless beasts attacking their captured companions and every human they came across. Thus the new Millennium was baptized in blood and slaughter, with these cursed pokemon becoming known as 'shadow pokemon' due to the dark aura around them that could be seen by psychics and aura readers. Shadow pokemon could be purified, but it was not an immediate process - and regardless of it, they would still become engulfed by the Shadow each time a new Age begun and the magic of the priestess was amplified.
The priestess - Alasenna - had stabbed a cursed blade into the very hearthstone of the Spear Pillar, severing Arceus bond to the mortal, physical world. Bereft of much of His power and almost even bereft of His life, Arceus escaped this dimension to stop Alasenna from absorbing the last bits of his power. But she was powerful enough - ruling over the power of the Elemental Plates and with all the non-legendary shadow pokemon under her semi-control, Alasenna had none who could oppose her. Now immortal and immensely powerful, she await the end of this new Millennium when her cursing of Arceus will be fulfilled, and the legendary will die. She can absorb his last bits of power then, and finally re-shape this very world to her her own desires and whims. A hundred and fifty years have passed since then, and the age of Moltres will enter the age of Mew in half a year from now. People prepare for yet another wave of shadow pokemon, no longer putting any hope in the Prophesy that promised them their saviors.
... but the time for the saviors have come. One night, as you sleep and dream, Arceus comes with you to awaken an ancient memory that you had forgotten long before your own birth..."
