They say it’s about 40% faster to watch. Which they say currently saves about 150 hours.

It’s a fan made project that cuts out the recaps, the filler arcs, and most of the OP and ED sequences, keeping one of each at the beginning/end of each arc. It then condenses a lot of the story arcs and reorders some events to (mostly) fix the pacing issues of One Piece and cut down on the run time while preserving the original story.

They’ve got a website out there, but I can’t link to it here, since it’s technically a pirate site. No pun intended. It should come up with a google search though.

Which is one of the reasons why I typically recommend One Pace over the actual series to people. It fixes just about all of the issues I had with watching the series. It also makes it easier to get caught up if you’ve lagged pretty far behind the weekly schedule.

It looks like it’s based on a story from the histories of middle-earth about the founding of Helm’s Deep.

They probably take a lot of creative liberties with the story, but it’s at least not entirely original.
