Well they started with uncharted 4 and ff7 then said "if we are starting with this imagine what else we caught"
We got randy pitchfork begging everyone to play battleborn.
1 hour of indies which was just to much even though I did pick up nuclear throne.
Then ended on another Moba that is going to come back next year with the leader of epic begging people to play it. Announcing Jacob the badass lemur.
Fair enough.
But i think the problem is a matter of personal expectation. Maybe for you the conference was a letdown because the amount of indie games, and i give to you that battleborn and Paragon aren't getting me hyped too.
But i saw many, many cool games announced and i personally don't care if they are indie or not. And we got at least one bigger games in Ni No Kuni 2.
