Pikmin 3, both Mario games, Paper Mario, and Luigi's Mansion 2 and were my picks of interesting stuff. Seeing the menu for the Wii U was nice I guess. Everything else was pretty meh or just boring.
The whole conference started sliding downhill after Harley Quinn stopped talking, which was disappointing considering how strong the beginning was. I was falling asleep near the end because of the sheer amount of third-party filler and unnecessary long demos (like NintendoLand's Luigi's Mansion thing; seriously, you can sum it up in a trailer and save like five minutes for the conference, maybe to focus further on Luigi's Mansion 2). Still don't know why the hell New Super Mario Bros. 2 makes Mario seem similar to Wario because of the obsession over coins; Wario could easily be the starring character. Speaking of him, has anyone noticed Game & Wario? Nintendo posted it on the website today.
To summarize, though, it wasn't horrible, but I think people slam on it too much and forget how much of a wreck 2008 was with its twogames and boring speaker (thank god she no longer is with Nintendo).
This is pretty much Nintendo's last chance aside from E3 to get me to play my Nintendo 3DS. Nintendo had better be thankful Level-5 is making games for them, because so far, the reason I have a Nintendo 3DS is for two Professor Layton games (not judging the soon-to-be-fully-shown Super Mario 3DS or any remakes they have planned). Until then, it's my favourite dust collector. I hope it doesn't have to stay that way.
