I liked Nintendo's E3 presentation the most, but it wasn't flawless:
Issue 1) Utter lack of new 3DS software this year is a disappointment and only one new game ,albeit an original title, STEAM for 2015.
Issue 2) Wii U's only newly game coming out this year is Capt. Toad Treasure Tracker. The game looks fantastic, but we aren't getting Xenoblade Chronicles X or anything else. I assumed we'd be gettin a bit more software than what we got. T omake matters worse, Wii U's in yet another software drought for summer.
Issue 3) Announced in January 2013 in name only, Fire Emblem X Shin Megami Tensei was once again absent from E3. Fatal Frame was announced like a month before E3, but again, nothing shown for it. It's becoming a bit frustrating when Nintendo does this some times.However, I suppose Nintendo gets a bit of a pass on these titles given how they did instead show a good amount of software coming in 2015 to make up for it.
Issue 4) One of Nintendo's goals this year was to highlight how their trying to make better use of the GamePad to show why its important to their games and why we should care. I think the results were a mixed bag. They showed some fairly interested titles that sued the GamePad in different ways, but there wasn't one particular title that made you a true believer in why Nintendo remains committed to it in the first place. By the way, not all games should have to use the GamePad in a big way if it doesn't make a lot of sense to (just as it was with some Wii titles) , so titles like Smash Bros and Xenoblade Chronicles X get a pass, but one would expect Zelda too use it in a big way, so we'll see how that game uses it out by next year's E3.
Issue 5) Nintendo still remained vague on the details of Amiibo. While the figurines look pretty darn cool, they do not appear to be unlocking anything essential to the core gameplay experience of the titles they'll be supporting. I remain skeptical about other ways Nintendo will try to use it, but we do know that Amiibo will continued to be used in next-gen consoles as well.
