Paper Mario: The Thousand-Year Door is the second game in the Paper Mario series and is widely considered to be the best. It was originally on Nintendo GameCube and is getting a full remaster on Nintendo Switch.
It’s a turn-based role-playing games, and as far as Mario RPGs go, it’s up there with Super Mario RPG (which is also coming to Switch) as one of the best Mario RPGs ever made. It was originally developed by Intelligent Systems, the same developer who makes the Fire Emblem series.
Good addition to the Switch library as the console’s life-cycle winds down. It releases sometime in 2024.
