The internet is full of reactionary idiots. You know this. Everyone knows this. The internet is a decent cross-section of humanity, and humanity is full of reactionary idiots as well. It follows that on-line communities would reflect this.
Last E3 was exciting because there were hardware announcements. The new consoles, which would help to dictate and define the nature of a good chunk of the industry for the next 8+ years were finally being revealed. Of course it would be more exciting. If you were just defining E3 by excitement levels, there was never any chance that this year would be able to measure up to last year.
You have to actually think about things, and read between the lines.
Microsoft was in a firmly defensive position for their entire show. They leaned heavily on pre-rendered, flashy cinematics for games that have probably barely begun development. Most of the titles that they "revealed" today won't be arriving this year, and possibly not next year either. While their show was big on games and big on flash, there was very little actual substance. The real stand-outs were the Sunset Overdrive trailer and a smattering of indie offerings. The Halo collection is nice, but it is a repackaging of decade-old games. Crackdown and Phantom Dust are both interesting, but we likely won't see either until 2016. Microsoft's press conference was well presented, but there was a constant undercurrent of desperation.
Sony's conference was longer, and much more poorly paced. But anyone familiar with E3 can tell you that this is nothing new. Sony always lags behind in their over-long E3 press conferences. In fact, they get bonus points this year by actually starting on time. (they are notorious for starting 20-30 minutes after their scheduled time) While they didn't have any truly big announcements, they were just as firm on their game messaging as Microsoft was. They also showed far more in-game demonstrations. It's much more likely that most of the games Sony showed will be arriving in the next 12 months. Sony was staying the course this year. They came out of last year with a big win, and this year was simply a continuation of a strategy that they can tell is succeeding. If only they could figure out how to pace their conference properly. They really need to hire someone with a bit more showmanship and theatricality.
I didn't get to see the EA conference, but I don't have a lot of faith in them to begin with.
Ubisoft once again had one of the more watch-able shows. Whoever hired Aisha Tyler deserves a raise. She's easily one of best presenters at E3. Her gender and ethnicity are automatic publicity wins for Ubisoft. The fact that she can handle herself well in front of a crowd, and clearly knows what she's talking about cements her place as a regular E3 fixture. She even dresses in a tasteful and professional fashion that reflects well on herself, Ubisoft, and the industry in general. Kudos Aisha, it was a pleasure to see you in your element again this year! Ubisoft's content was also respectable. They're going to get some racism flack over that Far Cry 4 trailer. But aside from that it was pretty smooth riding.
