I have created a new Mario RPG: Mario & Luigi: the Bowser's Shadow. The game Main Villain is Bowser who wants to have the 7 Legend Stars and to take over the world but one of them is in Peach's Castle and he is caught by Toad Police. Peach heard about the crime and she needs that Mario and Luigi get the other stars. The game will have a lot of Playable Characters. Mario and his friends will have to visit Yoshi's island or Dry Dry Desert if they want to take the 7 stars.
The game is a mix of Mario RPG and Super Mario Bros. There will be a lot of items, bosses, places and new playable characters. If you want to know more about the game you have to wait a little because I will add more information about the game. Have a nice day!! :)
