How would you know? Around the wii u release we heard about many awsome games like wonderful 101 and bayonetta 2. That system had a brand new mario and mario kart and still failed to kick off.
All we know is that it didnt sell out their initial shipment of 2 million ( unless that number wasnt true ) . For a system not to be sold out during release week is kinda a bad sign.
Dont get me wrong i am in love with my switch. But nintendo need to have direct asap and good exclusive games other wise people will start to lose hope of the system since it lack games
It's not hard data but the general feel and buzz around the launch is much more positive than with the Wii U, which launched into a cloud of indifference and public ignorance and confusion and without any killer apps except NSMBU, which always sells well but doesn't really sell systems (in my view anyway). There were a bunch of ports of major third party games which failed to improve on or even match other versions on last gen hardware which gave the whole thing a 'meh' sort of feel. Then Mario 3D World came out, which was a fantastic game but which managed to pitch itself in the public consciousness as a 3DS conversion as opposed to the next mainline successor to Mario Galaxy. The console itself lacked the "cool" factor, even at the time, that the Switch has now with the strange and unproven gamepad concept, which never really managed to convince the market.
The Switch 'buzz' is a lot better. People like the concept and the launch comes off the back of all the hype from the NES classic, which looks like a marketing masterstroke, stock issues notwithstanding. It also has the supreme advantage of launching with a game that the media has decided is an unmissable, all-time classic and which is probably selling huge amounts of units all by itself. The third party offerings are much weaker/ non-existent but I think that is actually a positive. Instead of pretending that this machine is an alternative to the Xbox or PS4 for mainstream games, and falling short of that promise, the Switch makes a clear case for being different and complementary and it can hopefully live up to that.
The issue, moving forward, is how to keep that buzz going. Zelda will stick around and Mario Kart and Mario will move things forward but Nintendo are going to struggle to support this by themselves. Indie games help but they are too niche to attract millions of purchasers and third party conversions - whilst they have the option of mobile play (although then there is the issue with online) - will probably show the Switch in a poor light. Ideally, third parties will make dedicated Switch titles but I'm not sure how likely that is outside of shovel ware.
It's a good, positive start and I think Wii U style failure can be safely disregarded but if this is to be an outright success its going to depend on whether or not Nintendo can attack the right sort of third party games. A good start makes this more likely but by no means a sure thing.
