This was one of the strongest E3s, by far. I actually stayed up for the live presentations, which I never used to do. All the major conferences were superb, so many fresh and exciting looking titles. The Last of Us II, Sekiro, Ghost of Tsushima, Kingdom Hearts III, RE2 remake, Fallout 76, Rage 2, new Wolfenstein, DMC 5 and of course, Cyberpunk 2077. And hell, even new AC looks really cool, the new RPG direction is what I like to see. Also, Control looks so intriguing, I'm expecting interesting things from that game.
...I reaaaaally need a PS4...not even accounting for the extensive backlog I have
Though, needless to say, Square Enix really disappointed me. They got some new IPs, nice I guess, but they completely failed to grip me in any way. Not even a mention of FF XVs 2nd DLC season and above all, FF VII remake.
But the coolest little surprises were the announcements of Yakuza series coming to PC, I was always hoping to play those. (here's to a smooth port) and the new Life is Strange, wonder how that one's gonna play out.
