In an attempt to get a Super Paper Mario guide out as quickly as possible, the team at WiiGuideYou is burning through the game at warp speed and putting up a chapter a day of their guide. Chapter 1 is scheduled to go up the 10th, and each day will see a new chapter, until the series (and the game) concludes with Chapter 8. They're even attempting to get Chapter 1's guide up early.
If they accomplish this task, it means that either they worked day and night at getting through the game to provide a guide, or that the game is really, really easy. If you don't mind the extreme spoilers that are, in fact, the whole point of game guides, then check it out and cheer them on!
