There have been a variety of Mario role-playing games released in the Mario series' history. The first was Square's Super Mario RPG: Legend of the Seven Stars. This game has never received a direct sequel, although as it was the first game to put Mario into an RPG environment. The Paper Mario and Mario & Luigi games are usually considered spiritual sequels. The next game was Paper Mario, which was later followed by Paper Mario: The Thousand-Year Door and Super Paper Mario, the latter being a platform game with role-playing elements — unlike earlier games in the series, which were role-playing games with platform elements. Another spiritual sequel was the handheld game Mario & Luigi: Superstar Saga, which had a sequel called Mario & Luigi: Partners in Time, and a third installment called Mario & Luigi: Bowser's Inside Story.
