I give it a D. It's the same bullshit they've been doing for over a decade now. The heavily-edited Avowed trailer tells me they don't want us to see what the real game looks like which is a tad alarming, seeing how close we are to the release date. The Perfect Dark "gameplay" trailer looked faker than a Ubisoft gameplay trailer and they gave Joanna a square chin just so they aren't doing a misogyny... Metal Gear Solid Delta looks like it's being made by toddlers with all those jerky starts and stops to animations and questionable character redesigns that look way worse than the ones from that pachislot tease... Gears trailer was a nothing trailer with a nothing date and a nothing year.. Fable had another nothing trailer showing that intentionally ugly female protagonist that marked Playground Games safe from doing a misogyny...
Outside of COD BLOPS 6, the four things that looked genuinely cool to me were the Compulsion Games thing with the catfish called South of Midnight, the new Doom, the Indiana Jones game, and Stalker 2 which looks like it will be an absolute banger. I'll go even further and give South of Midnight my best in show award.
Honestly though, I think Sony is doing the right thing here and sitting on what they have cooking until they can really show it off right. Just because the Xbox showcase Was A Fun Show, that doesn't mean a whole lot. They've been putting on "Fun Shows" and "winning E3" for years.
