"There are many ways to create games but the way we work at Game Freak may be a little different from other companies... we constantly change and tweak what we have come up with. To make a fun game even more fun and polish it up, we take what we have made and start thinking about it from scratch."
- Junichi Masuda, "HIDDEN POWER of masuda No. 7"
This philosophy of iteration and polish inspired Pokémon Polished Crystal. The project's creator states:
"I've always wanted to make a Pokémon game. Not just any game, but the best Pokémon game possible. What does that mean? I think a great Pokémon game should be like Gen 5: always offering new ideas and not being afraid to make changes. But it should also respect the player's time and make quality-of-life improvements. And most importantly, it should be fun!"
Modernization Without Losing Identity:
- Implements Gen VI+ mechanics (Abilities, Fairy type, Physical/Special split)
- Preserves Gen II's aesthetic and charm
- Offers both "Polished" (enhanced) and "Faithful" (conservative) builds

- Trade evolutions accessible without trading
- Running from the start
- Streamlined menus and bag organization

While Polished Crystal aims for the best possible Pokémon experience, some features are intentionally not included:
Mega Evolution / Z-Moves / Dynamax:
- Too complex for Gen II hardware limitations
- Would unbalance existing gameplay
- Focus remains on Gen I-VI core mechanics
Gen VIII+ Pokémon:
- Polished Crystal includes all Pokémon through Gen IV (plus Sylveon)
- Adding newer generations would exceed cartridge limitations
- Current roster of 253 species is considered complete
Online Trading/Battling:
- Hardware limitations of GB/GBC platform
- Focus on single-player experience
- Local link cable trading/battling still works
Following Pokémon:
- Significant sprite work required
