LOL, someone isn't going to sleep well tonight

Some things are easy, then it becomes harder and harder until you get into a point when you say "now I will consider all games equal".

For example, full game > DLC, easy to understand. Brand new announcement > game already announced but not yet launched > game already launched on other platforms, easy to understand too. Gameplay demo > trailer > teaser, easy to understand. AAA games > indie or retro games. And so forth...

Then, among new announcements, you can take it as more relevant a brand new IP (like Splatoon) or a sequel from a game launched many years ago (like Rainbow Six Siege) than, for instance, a game launched every year (like FIFA) or every 2/3 years (like Uncharted or LittleBigPlanet). Or you can regard more a game that everybody thought to be death than other that everybody already expects, despite none of them to be new announcements. For example, a gameplay demo of The Last Guardian or The Getaway 3 + a release date would definitely be more relevant than what was showed about The Order 1886.

I would stop here and consider from now on all games in the same circumstances to be equal (in order to keep a neutral position). But it's possible to go further and, like you suggested, look at critic scores and sales from previous games from the same series and, in case of a new IP, from the same dev.

Anyway, regardless how deep your analysis is, as long as you remain neutral and objective, Ubisoft is clearly ahead of Sony on this E3. Only a fanboy thinking "I don't care, that Uncharted 4 teaser compensates everything" could tell Sony was superior.

We all knew that already before E3. I think you are assessing the consoles rather than the conferences. In order to assess E3 you need to think: which company added up more value to its products' portfolio from 9th to 11th June?

The Meme Memo hasn't been updated yet, so folks are still reading from the old script. Take pity on him until then.

Nintendo's conference was amazing but it is missing a lot of major multiplatform games that we were promised to have since launch

I think I do. Sony has many and good studios. If each a every one of them doesn't show something new and relevant at least every 2 years, then they are either wasting resources or not spending them at all. Either way, that's censurable.

Maybe not enough but at least they are trying very hard to appeal to gamers again. They made a good effort and they showed its results on E3. Will the games take some time to be launched? Yes they will, that's natural and it may not benefit Nintendo in the very short-term like you said. But they will eventually come and, E3 wise, Nintendo was superior to Sony and Microsoft. I wish they had the same attitude as Nintendo is having now (probably forced due to bad results, but they're showing it).

Uncharted 4 was just an example. What I was trying to tell was that, unless one values more a certain Sony game (or several ones) more than Ubisoft games without an objective reason in a wise analysis (meaning that it's just tastes making the difference), there is no way Sony had a better E3.

Yes you can quantify the titles as long as you don't consider 3rd party games as Sony's work and you don't mix oranges with apples (for instance, DLCs don't count as much as full games).

all surprisingly manged to win.

MS won on improving and actually being likeable
Sony won on scope, 3rd partys exclusives indies hardware services
Ninty won on pleasing their fanboys more then ever

Yes, I think Nintendo "won" E3, but, to be honest, no one had a very impressive showing. This was one of the most disappointing and boring E3 shows I've seen.

Nintendo kind of won by default by keeping the running time short, demonstrating a sense of humor, and showing a lot of gameplay.
