You might be able to put Demon’s Souls, Dark Souls, and Elden Ring in a similar category, but there is no doubt that Sekiro was a fresh and unique title by FromSoftware.
Sekiro Shadows Die Twice was the latest legendary drop by FromSoftware before they start working on Elden Ring.
While there is nothing official about the next FromSoftware game, you will probably love this fan-made concept trailer for Sekiro 2 made in Unreal Engine 5.
Also, Sekiro had a more linear story-telling than the Dark Souls series, which made it even more enjoyable for newcomers to the Miyazaki universe.
