About the Game

Pokémon has always held a prominent place among my hobbies. When I was younger, I enjoyed assembling teams to challenge different Gym Leaders, Elite Four members, and any formidable Trainer considered a “boss battle.” The idea of creating my own game never crossed my mind until I played titles like Pokémon Unbound (by skeli and ghoul), Radical Red (by soupercell), and Inclement Emerald (by BuffelSalt). These hacks, in my opinion, represent the pinnacle of Pokémon experiences. What attracts me most to these games are a few shared characteristics: a diverse array of obtainable Pokémon, a sophisticated and modern battle engine, and, most importantly, a substantial level of challenge, masterfully exhibited in their intense boss battles. The concept of “boss battles” has always fascinated me, and after playing these exceptional games, I knew I wanted to create my own.

With the abundance of selflessly shared resources from this community, especially RHH, DizzyEgg, and PRET, I embarked on creating a game with a few guiding principles in mind:

  1. Difficult, yet fair – On a scale of 1-10, with vanilla being a 1 and Radical Red being a 10, I would rate this game at a 6.
  2. Aligning with modern entries in the series.
  3. Streamlining the player experience.

Concerning point three, while I appreciate competitive battling, I never got a kick out of stressing on EV training, maxing out IVs, or collecting Pokémon with ideal natures. Similarly, the requirement to grind for experience indefinitely is unlikely to appeal to the ordinary player.

The project was created to allow players to quickly fulfil their team-building objectives while still providing a challenge through increased difficulty. To be honest, my goal was to provide the kind of Hoenn experience that I would like playing. Despite the fact that the game largely follows the vanilla Emerald storyline, players will find new Trainers to combat and new activities to explore!

Taking everything into consideration, I am thrilled to offer my Emerald difficulty hack with the Emerald Horizons community.
