That they didn’t show off much of anything that we hadn’t already seen before and spent a good chunk of their hour talking about why they chose to do something with a property or what inspired them, which is fine in a typical Nintendo Direct, but seems wasteful for an E3 presentation.
I love Nintendo, but the only thing that remotely interested me was Starfox and even that just barely. Otherwise it all seemed to be killing time and casual games that are fine in their own right but nothing to push consoles.
AND THE FUCKING METROID PRIME GAME?!?!? GOD DAMMIT!
