Most of them weren't AAA games like people are predicting here. Don't get me wrong, there's going to be some BIG trailers here, but not a ton of them.
Dragon Age 4 Teaser
Far Cry: New Dawn (revealer earlier that day, but the trailer was at TGA, iirc)
Mortal Combat 11
Epic announced their store there, which was the biggest piece of news.
Outer Worlds was revealed there, too, as was Ancestors: Human legacy
Marvel Ultimate Alliance 3
We also had AA stuff that failed to pick up traction like Atlas and Scavengers
So, not really just indies, and there's a good chance of some major stuff showing up there.
