Princess Peach is hosting a game for everyone in the Mushroom Kingdom to play! The first person to get all 8 Power Stars from the various worlds of the Mushroom Kingdom will be granted a wish! Just make sure you get there before Bowser! A simple and silly adventure, Mariomon's story mostly focuses on the conflict from Bowser trying to get the 8 Power Stars before you. Otherwise, it's a pretty free form adventure where you're just trying to have fun in the game the Princess and Professor E. Gadd are hosting!

In Pokémon FireRed: Rocket Edition, you will cheat, lie and steal your way to the top as you engage with the thriving gang scene of the Kanto region. Featuring a story that takes place at the same time as the original FireRed, Rocket Edition will play with your expectations and allow you to experience the classic story from a whole new perspective. Along your journey, you will unravel secret conspiracies, explore a side of Kanto you’ve never seen before, engage with familiar characters in unfamiliar situations – and, most importantly: steal their Pokémon!
