Though it may have been originally announced for the GameCube, Super Paper Mario is now one of the most anticipated titles for the Wii. For those of you who are itching to see more of the game (and spoil some of the story for yourselves in the process), we’ll be hosting a 4-hour live gameplay marathon right here on this page. All GameSpot members will be able to tune in to this special event, and GameSpot subscribers will be able to chat with each other as the marathon moves along.

So join Ricardo Torres and Rich Gallup on April 6 at 1 p.m. as he flips his way through the first few chapters of Super Paper Mario, through the land of Flipside and beyond. For those of you unable to catch the live broadcast, be sure to check out the highlights reel we’ll be cutting together afterwards.

What: GameSpot’s Live Gameplay Marathon – Super Paper Mario
When: Friday, April 6 at 1 p.m. PST
