Of course nintendo won the E3, because nitendo wins every E3 ever!
Well, that might seem like an overstatement form a rabid fan. It is. I'm a fanboy and what not and that is exageretaing. But for me it is the truth. Why? For simple reason, Nintendo does their own thing.
And that is the reason for me to own a console. I don't want a PC with a closed platform and a controller. I want a game consoel, something that gives me an experience completely different that what I can get with a PC. And that si what Nintendo has deliviered for years to me. The way of playing and the games to be played in nitendo consoles are jsut Nintendo doing their own thing. That can be bad to some people but I like it. I like that they havce their vision and stick with ti, ignoring the industry trends and focusing on doing their way of doing games. It may not be for everyone, but know what? that is good, because it hasn't to be tailored for you, it has to be made with passion and heart. And that same passion and ideas go into the hardware.
Most of the games may be the classic IP (I would say that at least once a year we have a new or very old IP revivied to coutner that) but well, sadly if that is how it works in the industry it is part of our fault (we tend not to buy new things). But the other consoels only give me experiences in general that I can find in my PC, so buying one is almost redundant. "Hey look Titanfall looks like my kind of game, but well, I get it on Origin with controls I like better" to "hey Smash brother is doing great, is only on Nintendo and focuses on local multiplayer which I can't get on my PC". That is how I look at the difference between console nmaker. Yes, there are exclusives I would buy a console for. But Nintendo is unique in both hardware and software. Even things that can work on other platforms, liek a competetive TPS is done in a Nintendo fashion, trying to see it in a different light with a new IP (Splatoon) and even if ti doesn't cathc it was their idea and they tried it.
So every E3 I come excited about the Nintendo conference and get out exceited for the new things to come. Because Nintendo is in my heart, and they now to be their thing. So yes nintendo won for me, but that is because of my love and perspective on games and gaming industry. Not that the otehr are bad, this is just how I feel. Nintendo not for you? Well, I don't mind. But I will have my Zeldas, Marios and Splatoons and love every second of it. There is no objective winner, but a company has my heart.
