I watched the intro video and still have no idea what this app is or does.
Now I have to do a Google search.
It's obviously a video game. The real question is, what kind of game is it? And this question was not answered by the video. Plain and simple.
I won't defend the site design - it should be easier to get to https://supermariorun.com/en/about.html, but it still takes very little effort to find this.
For me, the fact that it is a game named Super Mario Run, made by Nintendo, for the iphone, instantly tells me that it will be a side scrolling runner-style game featuring Mario in Super Mario Bros style levels, with basic touch controls. In fact it occurred to me that I hadn't verified these assumptions and I just checked out the about page and found that it looks exactly like I expected.
I guess some people make the exact same assumptions I do, and this is totally not obvious to others, hence all of the miscommunication and arguing in this thread.
You got lucky in assuming what the game would be about. If you had done the same thing with other games (e.g. Pokemon Go) you would have completely missed the opportunity to discover a new kind of game.
I advise not judging things by their cover, unless you want to risk not discovering something new.
The ad is very confusing without context. It's not super clear, but you can close the video using the exit in the top right corner and then click "About":
That's like me saying "food" when asked "What do you wanna eat?"
I'm guessing you aren't a gamer. Most gamers are not interested in the binary question of whether something is a game or not -- they are a step ahead of that.
What you said is not true at all, and frankly, it sounds arrogant (which I don't mind, except in this case, you're wrong).
Let's go ahead and apply your logic to Pokemon Go: "It's an iPhone game named Pokemon Go".
That statement tells me nothing about Pokemon Go. I speak to you as someone who has played over 1200 hours of Pokemon Red, Yellow, Fire Red, Sapphire, Emerald, and Diamond. Gamers are experienced and humble enough to know that "Super Mario Run" could mean almost anything. Do not make the mistake of underestimating game developers, least of all Nintendo.
I posted a comment here about my first impression of the game's title:
"First thing that popped into my mind was Pokemon Go, but for Mario. Is this a Mario branded game which gamifies running in real-life encouraging kids to run to various locations to find coins or something?".
Other people on HackerNews seemed to share this viewpoint! It turns out this is not at all what the game is about.
You're missing some context here, as to someone who plays iPhone games the word 'Run' suggests that the game is an infinite runner[1]. So "an iPhone game named Super Mario Run" does imply more information (that it's probably an infinite runner, which is not quite correct, but reasonably close) than your Pokemon Go version.
[1] see Sonic Runners, Rayman Run, etc.
It was a 120s video. Showing gamers 5 seconds of game play would have told them about 70% of what they'd want to know.
