The showcase only showed us a few new announced titles and more of the same reveals that were recently revealed.
Square Enix has just released their E3 2018 showcase, but the 30+ minute livestream show seems to be a lackluster, as most of the reveals were previously premiered a few hours ago and some were already announced titles felt that had additional footage. It could be possible that some of the big reveals will be announced later from the Sony and Nintendo presentations, which will be seeing in a few hours.
But for now, here are some of the games that were revealed at the Square Enix E3 Showcase:
Shadow of the Tomb Raider
Final Fantasy XIV Online new patch and Monster Hunter World collaboration
Dragon Quest XI: Echoes of an Elusive Age
The Quiet Man
Just Cause 4
Kingdom Hearts 3
