Actually now that we're on mobile games anyway, why are the games NEVER like they actually show in the ads?! Why don't they just make those actual games and not the fake **** that takes up 99% of the actual gameplay?!
I know you asked this ages ago, but it's because these mobile game companies just pay for ads that some company makes, very few make their own ads, which is a lot of the time, you can see different games having similar ads. They mainly spend their money on advertising so they can get as many people to watch as many ads as possible. Some of these companies purposely mislead people because the games are really basic, such as a generic match 3 or clash of clans clone so they purposely mislead in order to make people think that it isn't a candy crush clone, and a semi decent game which takes more money, as these games are only made to money not to make a game. (which actually works really well)
Mobile game advertising is an extremely weird but interesting topic, basically using everything advertising tactic in the book, along with just straight up lying in order to get ad revenue. It's sustainable because enough people play them so that they still make ad revenue. And that they haven't been taking to court/taking down because it would be a waste to, it's not like these companies are taking money from people, they are just using them to make money along with that it is extremely quick to set up these operations.
Got a lot of this info from this article and some reddit posts interesting stuff -

It seems to have a similar structure to a game I played for a bit called devil daggers, really fun fps where you had to run around and survive in an arena, that was addicting but really hard.
