no real presentation on stage like other companies, just a recorded video like last 3 years. no announcement like "annnnnnnd now meet Reggie on stage ! annnnnd now the switch will have this and that feature coming this year, DLC, apps, netflix, VC consoles, etc."
it was short and didn't have a lot of announcement, while they said "wait for E3, it will be great this year!"
not a lot of game we didn't already knew.
And one bad thing : They decided to go with "let's show new unannounced games after the E3 presentation, AFTER people stopped watching the streamed video, very good advertising choice!" again, their marketing and communication branch sucks. who hired that guy?
I would have presented Samus return first (for the big surprise), and at the end of E3 just tease with MP4 being in development for another ending surprise announcement. but hey, I'm not nintendo's communication director.
Metroid Prime 4 : announcement, nothing to see. it's good I guess, but they could have announced it even if there's nothing in the work for real. "let's add something to that poor e3 presentation, we can announce something we don't have yet instead of showing that game we have? good idea"
Xenoblade chronicle 2 : could/should have been named something else, it's not a sequel. reminds me of Sky of arcadia. It looks good.
Mario RPG + Rabbids : could be better than I thought. good visual and game play. seems fun to play but maybe long and repetitive (like all tactical RPG). Let's keep an eye on it.
Next mario game : I'm not a huge mario's game fan, but it looks "okidoki". just fine, but not that great to me for what I saw. levels are a little empty, controlling the game seems weird (or the guy doesn't know how to play it). possessing enemies is a funny idea though.
That's all I noticed which got my attention.
for the moment, only the first 2 games I'm interested in playing. That's fine that they don't have anything interesting until 2018 because I still have too many unfinished games to play
edit:
Metroid Samus Return : Great visual, good surprise, I'll remove the dust off of my 3DS !
