And, as for Super Hexagon, I'll play anything Terry Cavanagh makes. He is a fucking god. 4-Letter-Word melted my brain.
1. write crap game. 2. buy reviews. 3. profit.
However, if your app is awesome, that initial burst of cheating allowed your game to push through the crowds of 50,000 other apps to get the eyeballs it needs. If it's a great app, those initial users who were suckered in by cheating the system, are now happy, satisfied customers telling their friends about your app. You don't need to game the system anymore: you've broken through the brick wall that is the first 10,000 or so sales. After that, you can rely on the quality of your game to win people over, but when you're naked, alone and review-less, the app store can be a terrifying and unfriendly place.
The way you are describing it basically makes it sound like a hidden listing cost to be on the app store.
Eventually though people are simply going to stop believing reviews at which point Apple/Google will have to start taking some action against this.
I played 10 levels of this game on the web site, though, and it never even encouraged me to brag to anyone else about how quick I solved a puzzle, and had no replay value, e.g. I can't solve a puzzle better or worse really. The game has nothing to get each user to draw in more users, so it would be a waste to do the ad spend at all...
A crap game doesn't get good reviews, so boosting the app rating by buying fake reviews is just throwing good money after bad.
Anyway, I wonder how long will it take before this tactic becomes too widespread so that only huge players will have enough cash to game the system like this.
I don't want to sound cynical, but why do you think it hasn't already spread so wide that only huge players can game the system enough to gain the top spots? There was an article on HN this month about how book publishers even game the NYT book rankings.
