I'd give it a C-
Hololens looked cool, but I'm always weary of prototype tech until it's fully released.
Halo trailer was a decent start.
BC was a nice extra, but BC has never really been a mass market selling point, especially when you're talking two years post launch.
I'm sure someone will like that controller, but definitely a niche product.
Cuphead looks cool, still coming to PC AFAIK? Indies getting some video time is always good but most could be in Sony/Nintendo conferences just the same.
I was only half watching the presentation and honestly thought the Gears video was of a Gears 1 Remaster, not of Gears 4, I could see so little, not a great way to wrap up.
FO4 mods stuff could be cool, but unknown if it's also on PS4 and still better to just get the PC version.
Tomb Raider looked solid.
EA...
Forza 6 was Forza.
I don't give a damn about CG trailers when it comes to relevance to the games they're supposed to represent.
Conference should have been half as long, had EA stuff presented by MS in about 15 seconds, a Gears demo that was actually visible, and even if the rest was the same that would have bumped it to C/C+. Simple not enough actual 'Here's an awesome new exclusive with gameplay footage!'
