Description
Looking for a classic Pokémon experience with a fresh twist?
This game is perfect if you want a nostalgic adventure with a more mature story (but nothing too dark or edgy), modern quality-of-life features, and a few cool new ideas.
What to Expect:
It’s not a super hard challenge or focused on Nuzlocke play.
It’s not filled with Fakemon (new, fan-made Pokémon).
It’s not trying to be the next big, flashy hack like Pokémon Unbound.
It is for players who grew up with the original games and want to feel that same magic again—with a bit more depth and polish.
If you enjoyed Pokémon Gaia, this might be right up your alley.
Overview of the Story
Welcome to Cormoria, a brand-new region full of exciting places to explore!
Join your team of companions as you journey through icy mountains, active volcanoes, swampy marshes, busy city sewers, and much more—all while searching for the missing Professor Tenebris.
Uncover the secrets behind the mysterious dreamstones she discovered. What makes them so powerful? And what is Team Somber planning to do with them?
It’s up to you to uncover the truth and stop their dark plans before it’s too late!

Gameplay loop changes
This section is for those who are interested in some developer commentary. In Pokémon Dreamstone Mysteries, I’ve implemented some never-before-seen (at least to my knowledge) changes to the core game loop. These are small but impactful changes to the progression we all know and love.
- Undertake challenging journeys: Most of the routes in Pokémon Dreamstone Mysteries are blocked off from behind. You can’t go back. This completely removes to “go-back-to-PC-and-heal” gameplay and encourages the player to prepare for a real journey. In testing, I’ve found it to create gameplay sequences more tense and engaging than the regular loop. Some compensations have been afforded: there is a one-time Nurse Joy on every route and healing items are cheaper.
- Truly grow with your team: Grind removal isn’t like most other games. Most games either want you to grind endlessly, or just hand you a stat editor and spreadsheet. Both are fine…but neither are Pokémon Dreamstone Mysteries. The intent in this game is to have you truly grow with your team. You will start off with weak Pokémon. As time goes on, you’ll strengthen your Pokémon, one mint at a time, one vitamin at a time. And as you do this, you’ll stop seeing your Pokémon as stat sheets, and start seeing them as the cherished partners they were meant to be.
- Meaningful choice-based gameplay: This isn’t about “being the good/bad guy”. This is much more granular…and much more impactful. For example: people don’t just give you items – you choose what you want. Such choices are small but meaningful. Adrenaline Orb to counter the gym leader with Intimidate? Or Shell Bell with its healing? Normal Gem vs Silk Scarf? Feebas vs Mystery Egg? With the compounding of dozens of these choices, each player is guaranteed to have a unique and memorable run that they designed – without them even knowing it!
