MS, I know its 3rd party/multiplat galore but its all about showing games at the con and they did that.

I just read summaries about what they showed, so my opinion could be wrong.

MS by default for unveiling numerous new games and buying studios is long term potential.

Sony was focused like updates on games we knew about with some multiplat stuff.

Nothing Nintendo showed impressed me, but ultimately I think each show appealed to their respective audience.

Crappy E3.

Bit of a toss-up between Ubisoft and Microsoft. Sony and Nintendo fizzled out, though thankfully not nearly as bad as EA or Square Enix did

My final rating:

Microsoft/Ubisoft: 8/10
Bethesda: 7.5/10
PC: 7/10
Nintendo 6.5/10
Sony: 6/10
Squeenix: 3/10
EA: 2/10

Didn't see Devolver or Limited Run Games yet, but since they're bot very different, I leave them out anyway

Yes this. I judge conferences on the exclusives so Sony was far far superior in this regard.

But if you were looking at everything else i agree MS was better.

I wont make a comment on Nintendo as i didnt watch and nothing i have heard makes me want to. 

If you after looking deep into your soul can confirm that the real reason  for your fervour is in fact Anthem and not because you where hoping they'd go biannual with FIFA and Madden. then the hunts off.

 word of advice never admit to anything follow the teaching of  the great philosopher  Shaggy  with it wasn't me;

Overall, everyone underwhelmed me. Microsoft wins at putting on a good show, but it all fell apart once I realized that almost the entire conference didn’t make the Xbox One any more appealing. Sony did better with making me want a PS4, but where were the release dates? Could these all be PS5 games instead? As for Nintendo, I generally liked what they showed, but there was a lack of content. Overall, I’d give all of them a 6/10.

Square Enix phoned their presentation in 100%. 4/10.
Ubisoft’s flow was really weird, and there was only a couple things that interested me. 5/10.
Bethesda announced some stuff I want, especially Doom Eternal, but utterly dropped the ball with the presentation side of things. 6/10.

As for EA... Oh god, where do I even begin? Their presentation was super long and was mostly filler. They showed almost no gameplay. They tried to give us phony apologies for the lootboxes. They failed at revealing a Star Wars game properly. They dropped an Amiibo Festival-shaped bait and switch turd with Command & Conquer: Rivals. This belongs in the pantheon of terrible E3s containing Konami’s 2010, Sony’s 2006, and Nintendo’s 2008 and 2015. 2/10, and only that high because of Unraveled 2.

From the big three, MS won by far, but Bethesda was the one I enjoyed the most. Underdogs won.

I think MS in terms of showing game trailers which is what E3 is all about. But in terms of actual games coming from the studio I would say I liked Bethesda's the most, it was fun, and had some nice content. Sony's for AAA exclusives.

Disappointing E3 overall, but Microsoft's conference was the most enjoyable.

They take the "win".
