Just because can play the title on both platforms doesn’t mean that Sea of Thieves is the same download size on both; we found that the Windows PC version is just sliiiiiightly larger than that on Xbox One X and Xbox One S. Thanks to a reader, we now know the original Xbox One download is about half the size.
Sea of Thieves download sizes
- 9.16 GB on Xbox One (thanks, readers Matt M and Robbie S!)
- 18.73 GB on Xbox One X, Xbox One S
- 19.61 GB on Windows PC
