Why so many people have watched the video? The game has sold almost 4m, but  it  was released in the end days of wii though, mario party franchise aggregate sales have surpassed 40m  as of mid 2015....

Youtube videos related to Mario games ( or merely mario ), generally gather insane view counts but this has gone too far...

Is mario party the best franchise for  a mario game on mobile?

P.s  Do you imagine how much money has the video uploader earned with that simple gameplay video...

It's via a YouTube technique called, viewbotting, botting, whatever you want to call it. You buy software from a company that sends "fake computer IPs" to view you video or give you subscribers. This is one of the reasons YouTube has the great YouTube purge to try and combat it. If a video like this had 100M real views, it'd have waay more comments. The owner of the channel is cheating.

what... wait what!! o.o why it has so many views?

Makes sense now. But this phenomenon happens with practically every Mario Party game, as well with other Mario games, main and spin-offs included. 

Videos that get 5-10 million is understandable...but 100Million is viewbotting for sure. Especially for a game like this that didn't sell that well. Notice that about 50% of the comments are "How'd the video get so many views". Also, viewbotting isn't illegal I don't think... so I guess that's why it's so widely used. However when it comes to compensation, I think Youtube and Twitch verify the IPs before the content creators are able to recieve payment for views/likes/ traffic in general. It's not just mario party though, it's happening with a ton of other Nintendo franchises as well.

Edit: The user has also had 234,326 subscribers for some time now. You'd think he'd have more with all those views...at least one more.

Everyone is just making sure they know the mistake that was Mario Party 9 for future reference.

Cool stuff, my friends and I loved and played the hell out of MP9. That' soccer bonus game was the best and highly addictive!

There are many highly popular videos where the uploader has very few subscribers (sometimes under 100), so I don't think that's exactly a strong point.

It's been at that number since I last posted on the video about 9 months ago... Somebody replied to my comment and said it was viewbotting. Here's his reply:

"It's called view botting. People who uses a third party resources can alter the amount of views, subs and likes. It's so simple to use!"

A video with 100 Million views isn't going to not gain a single subscriber over 9 months... thus is the limitation of view/sub bots. Please be smarter than this, it's viewbotting.

I'm not saying that I don't think he's view botting.  I'm just saying that many youtube channels have videos with many views, but not as many subscribers.  

I can think of two channels with less than 1m subscribers that have at least one video with 30m+ views, and several others with a few million.  

All I'm trying to say is that, especially for certain kinds of videos, people don't really subscribe.  

There's also the fact that in your original response, you didn't specify a time frame.  Just "some time now" (which could be almost anything).  Then there's the fact that there's hyperbole.  Then there's another thing to point out, which is that pretty much every youtuber has been hit by the subscriber purge, and definitely was within the last 9 months, so there's also the fact that it probably did go up and then down again, coincidentally to the same number as you last checked.  

I'm not saying that IS what happened, but it's not unprecedented (with the particular point of low sub count, high video view count).
