Basically, really shitty game devs steal ingame footage from other less-known games and then slap their game's name onto it in an advertisement.
This post for example is advertising some sort of flying simulator or whatever that looks like it could be half decent for a browser-based game, but in reality the game itself is a 2D shitshow that was quickly thrown together and tied to a greedy cash-shop.
When these games gets too much hate (or lawsuits?) they close down and open under a new but similar name.
This seems to be a fairy new tactic (at least through Facebook ads), but in the past this same game (and a few others) has adverted with half naked ladies on ad banners instead of stealing footage from others. So the clickbait itself is still pretty constant, their methods have just changed lately.
Here are some examples of their game's art lol
Edit: And here is the actual game, which is nothing like the video or the art they advertise with
Don't click this shit and don't support their games!
