Spoiler-light introduction

What kind of adventure is it?

Modern Emerald deliberately keeps the original Hoenn story, towns and progression. Its purpose is to make that campaign much more flexible: you can preserve a mostly classic ruleset, switch on modern mechanics, or build a custom challenge before leaving Professor Birch's introduction.

Pokémon availableThe developer documents 423 Pokémon across the game and postgame, including 44 added species—mostly Generation 4 plus selected later evolutions.
