I don't think the content was that bad, I just think the poor reception of the conference was a result of poor presentation and a scattershot approach.
The conference felt flat, and rarely excited the audience or myself, watching it live. Galaxy 2, Golden Sun and Metroid were very pleasing trailers, but that accounts for only a few minutes of an hour. The NSMB Wii demo didn't convey the game particularly well, I don't think it was a good choice for an on stage demo. Impressions on the show floor were much more positive. Cammie and Reggie never really seemed particularly enthusiastic about their products, but I think Reggie did a better job than Cammie.
One massive problem Nintendo have with E3 is the massive audience they now have to appeal to-that's why I described it as a scattershot approach. They hit some targets, but definitely missed others. They veered from great games to games that didn't seem to belong in an E3 conference. The mixed DS titles come to mind as something better shown at a press briefing for investors, not E3, which is supposedly the gamer's show and supposed to be for the biggest and best content the industry has to offer. The show needs to be tighter-less emphasis on graphs, sales and demographics, and more about successfully demonstrating what products they have coming out. They may have failed to demonstrate NSMB Wii effectively, but I thought the Sports Resort demo (if you ignore Reggie's smack talk) was great. Those are the type of Wii demos that excite players: demonstration of a great, refreshing interface, examples of how a certain game will change the way you play.
Overall, I think the content was very good, much better than last year. Galaxy 2 was a pleasant surprise, NSMB Wii looks like a great local multiplayer game, Metroid has me very excited and I thought they'd given up on Golden Sun. The so called core montage at the end of the conference was disappointing-for me, they could have chosen much better games to demonstrate. Sin and Punishment 2, No More Heroes 2 come to mind-they were given no time at the conference.
And as others have said.... Zelda. Yes, details popping up the next day were welcome. But why not show the art work at the conference, just a tease? Why not announce the details there, before moving on to Galaxy 2 and Metroid? Or move onto Zelda from Galaxy 2 and Metroid?
The biggest low point was Iwata's ramble about the Vitality sensor. Don't get me wrong, I respect Iwata immensely. But the message was vague, and with no demonstration of software it seemed like a waste of time. You can bring out the Wii Fit comparisons, but that was unveiled as working software and was a clear demonstration of what to expect from the product. Vitality sensor was vague and detracted from Nintendo's better content.
So, much improved over E3 2008. Better, more varied content but flat presentation. They have many areas to tweak and improve on before their next conference. The good thing is they learned some lessons from last year, and with them again admitting the conference was disappointing, the signs are they'll learn some more lessons and improve again.
I have a feeling next year will be a very good year for Nintendo's fan base. Lessons will have been learnt, and a more consistent software lineup should be the result.
