Description
Pokémon Polished Crystal is an enhanced version of Pokémon Crystal that fixes bugs, incorporates official updates from later games, and introduces new features. It restores content from R/B/Y and elements from HG/SS while refining the overall gameplay experience.
Storyline
The core story remains the same—you start in New Bark Town, take on the Johto gyms and Elite Four, and then travel to Kanto to challenge Red. However, the game now includes new Pokémon, moves, maps, events, trainers, items, and a few surprises. Red is no longer the final challenge, and the difficulty has been increased for a more engaging experience, though further balancing may be needed.
Features
Summary:
- 253 Pokémon, including some new evolutions.
- 48 new moves, 75 TMs, and 31 move tutors.
- Modern mechanics, such as the Fairy type, Physical/Special split, Natures, Abilities, and more.
- Unlimited TMs and quality-of-life features like Running Shoes and continuous Repel.
- New/Revamped Maps: Some from R/B/Y, some devamped from HG/SS, plus original locations.
- New Characters including Lorelei and Agatha (R/B/Y), Lyra and the Team Rocket Executives (HG/SS), and others.
- More Post-Game Content: Gym Leader rematches, a new event after battling Red, and more.
- Improved Level Curve with steadily increasing challenges.
- Music and Graphics devamped from newer generations.
