The deep connection between each entry in the franchise is part of what makes the series so difficult for many new players to get into, and the final update of Kingdom Hearts Union χ ( KHUX) added even more ties to other games.

In the eyes of many fans, the Kingdom Hearts timeline seems to grow more and more complex as the series continues.
