I've watched it a few times, there really isn't that much in there. It gives high level goals of the game and not much else. Plus, this is a meaty game for sure and I can't imagine FS blowing their. . .shot like this in a six minute video. Reminds me of some of the gameplay videos from CP77: most of it was pretty much cribbed from the prologue before you even got to the title screen.
Looking at OPENCRITIC, 9 out of the 122 reviewers were posted after Feb. 14 and only 4 after release. I'm highly dubious of the main content size being the issue. It is almost surely people potentially beating their heads against a wall and a review timer.
Well, the DS3 launch trailer basically showed like 90% of the bosses and CP2077 legit had the ending scene in the launch trailer.
That being said, I don't think they showed us anything too meaningful and if they did we probably have no context to what is going on anyway.
