True but ya know...
At least remember...
No man sky was a thing... <_<
I'm excited for 2 things right now:
Shadow of the Colossus Remake - Because I already know the game is good and I've been wanting an actual graphically upscaled version for awhile. I see no way for me to be disappointed here.
Monster Hunter Worlds: Because Monster hunter is just an entertaining franchise for me, having it finally return to consoles (and PC), I again have little reason to become disappointed from this.
Even with those being my only interests so far, I see no reason not to get some enjoyment out of what companies bring to E3, even if I expect games to end up crappier than what they show me, I still love seeing the work they put into the Cinematics and early gameplay they show the public to catch eyes.
E3 is fun and enjoyable, as long as you don't try to take every thing that happens there at 100% face value. But this is true of anything in any industry.
As a side note, a lot of the other people I'm seeing enjoying E3 this year are getting excited over remakes, things they've experienced before and are just happy to see with a slightly updated paint job.
