Not only Nintendo? So vita must sold amazingly and make ps4 sales look like nothing compared to it, right?

Well, yeah, just checked the lineup from the 2 first years and almost nothing worthwhile came out in that time, and what was worthwhile is either already on the Switch or announced for it. Except the first non-release title, FF XIV: A Realm Reborn, I couldn't find anything to seriously push the PS4 which the Switch doesn't have or get.

But damn did Sony fuck up that Japan launch. Even the Wii U didn't have to wait for 2 entire months (February 22 to April 14) before the first non-launch game came out there. And that was just one game, the next one came 3 weeks later, and then 3 weeks later 2 other games. No wonder the Wii U outsold the PS4 there for a while.

But i think someone here said as long as it is a portable, it is destined to sell well in Japan just like the Switch no matter what?

Did you read my last post? Or you simply deleted all lines apart from the first 3 words I wrote ?

Games like Super Mario Party, Pokemon let's go, SSBU and New super mario Bros U Deluxe have created momentum, guaranteed, but can it be the only reason?  I think this Switch became the cool thing to buy in Japan, and NA as well, for a combination of reasons, and one could be its Social System, no need to elaborate about this; generally consoles sell mostly because of games, not because they offer such an enjoyable, unique experience that using the system itself becomes a selling point. Nintendo has moved to a completely different direction; the games are going to sell because of the hardware, and with this I'm not saying Switch hasn't great games ;)  It is also very smart and cool if you have kids.  The Switch is also yet another Nintendo system that looks and feels like a toy, and I mean that in a positive way!     Parents feel safe letting younger kids to play with the Switch, and the biggest and best games appeal to just every demographic, built in easier modes so that kids and parents can play together and have fun, from the co-op mode of Super Mario Odyssey to the racing available in Mario Kart 8 Deluxe.  This kind of trend and feelings is spreading more and more as time passes, this could play a fundamental part in the YOY peak.

Someone also told me God and the tooth fairly were real. Doesn't mean it's true.

In reality you need a great line up to not flop but you also need portability to reach your maximum potential in Japan. 

Is this really confirmed?..
