I've been back to playing PokΓ©mon lately and was glad to find a few newer jewels, both Rom Hacks:
1) PokΓ©mon Odissey
Completed in 2025 and with a sequel in the works.
Seriously, this is the single best Rom-Hack I've ever seen - and I've played quite a few. The ammount of care that has gone in the world building, balancing and fine tunning of the game is just leagues away of any other hack room I've tried.
The story is nice and extensive with pacing that never gets boring, characters are good (including the protagonist, who actually does have a personality), stakes get progressively higher. Not as good as Reborn, a few plot holes maybe, but overall very good.
It is an exploration and story based game, no Gyms (although each Stratum has a Captain that acts as one, and they all are actual relevant characters), no Elite Four, a ton of side quest content.
The world itself is beautiful - suffice to say that it has been heavily based on the world of the anime "Made in Abyss" and manages to do it justice.
Not all PokΓ©mon are available, but the roster the developers chose is great. Many are present as great looking, fantastically well made regional "Ethrian" forms, based off monsters of the RPG game "Ethrian Odissey", the other source of inspiration for the game. No Fairy type, but they added a really neat Aether type that ties into the story and is fun to use.
2)PokΓ©mon Elysium
While not in the same technical level of Odissey, it is an extensive game with loads and loads of content (so much so that it had to be split in part 1 and 2!) being the longest rom hack I've played by a decent margin. The story, though kinda edgy at times, is good, high stakes and kept me interested all along.
What really, really shines in Elysium is the character writing - from the pokemon professor to the Elite Four, passing by the sass queen of a protagonist, they are all memorable and the dialogues can be dowright hilarious. Definitely worth checking!
