I think I posted these somewhere else but since this is an "aftermath" thread I think it's better here.
Bethesda: 10/10 - Fantastic conference, the depth of Fallout 4 is staggering. Everything was just "here it is" with no blabbering. The announcement of an immediately avaialble product is always nice, and in this case the app itself is great as well. FO4 looks incredible and I can't wait to sink into the rabbit hole. Not particularly bothered about Doom, but everyone went into this expecting Fallout 4 and they delivered.
Microsoft: 9/10 - Backwards compatibility, ALMOST 'nuff said. Forza 6 demonstration was short but incredible. Not much else to say, this one just clicked and Xbox BC is easily the biggest announcement from E3.
Square Enix: 7 or 8/10 - Just Cause 3 alone. I didn't even watch anything past that, the game just looks that good.
Sony: 7/10 - Solid conference, I appreciate the quick firing of their games, but the most interesting stuff wasn't exclusive. Shenmue being brought back is amazing for everyone, but the way they're treating it is weird. Very surprised at the complete lack of any racing content.
Ubisoft: 5 or 6/10 - Not much I was interested in, but Trackmania looks great, and another title receiving a broader audience of consoles + PC is always nice for everyone. Ghost Recon looks great, but as with EA, the most interesting stuff didn't have much spotlight. Assassin's Creed is bland as ever.
EA: 3/10 - Not interested in Battlefront. All graphics and not much else really. The most interesting thing there was NFS, which got about a minute of screen time. The Unravel game looks decent and quirky but not my thing, and the rest was just SPORTS SPORTS SPORTS.
Nintendo: Didn't watch it, and this is the important part. But from hearsay alone, 1/10. From what I've heard even from dedicated Wii U owners, there's not much reason to keep the console. Reading the news of announced titles, nothing interests me either.
