Sony - 9/10, an energetic effort with colourful indie games, warmth and personality, little in the way of brown generic shooters, and funny in places. Combined with a staunch pro-consumer message, its one of the best E3 shows in years.
Nintendo - 2/10, after watching two days of HD streams, Nintendo couldn't broadcast a pre-recorded clip correctly onto the internet causing devastating buffering. New Mario looks just like an old Mario, new Smash looks just like an old Smash, new Donkey Kong looks... well, you get the picture. It gives an impression that the company is taking the NSMB approach and replicating it across their product lines.
Wind Waker HD appears to be so lacking in any actual new content that "1080p" and "filters" are the selling points. The other games we've seen before. Little to no effort in terms of the software being displayed, or the presentation itself. Boring, and no Wii U for me for at least another year.
Microsoft - 1/10, generic shooters, planted audience cheers, scripted to the point of being stiff, very little in the way of eye-catching, and did nothing to address the massive concerns about their current anticonsumer antiprivacy policies. Whereas I think I want to own a PS4, and will eventually in a few years buy a Wii U, this conference made me actively not want to be in the same room as the XBox One. A disaster.
