Total War: Three Kingdoms has had its release date pushed back and will no longer be out on March 7. Instead, we can expect to see the game released on May 23.

The news came this afternoon via a developer update. It's shaping up to be a bit more complex than previous Total Wars, so it's being pushed back to give the developers "more time to make sure these systems deliver as intended." Creative Assembly is well aware that fans are going to be disappointed at the delay and go on to say that this is the "best thing for the game and our players."
