This one may need a bit of context...
Dungeon Keeper is available on Apple and Google store, like all games there, you can rate it from 1 to 5 stars.
The thing is, when the game asks you to rate it, if you pick 5 stars you are sent to the usual store rating page (where you'll need to pick from 1 to 5 stars) but if you choose 1-4 stars, you are presented with a e-mail form asking you to write EA your feedback but your vote will not be counted. The result is only people who choose 5 stars are being counted and the result is the game having a 4 to 4.5 star ranking on the store. It's shady, it's evil, it's EA.
On Metacritic however, it has a astounding 0.2 consumer rating. Mostly because the game is heavily Free-To-Not-Wait to the point of being barely playable if you don't buy gems with waits of 24 hours to mine a single block in a game based on digging blocks to build your keep.
I already think this kinda of Free-To-Play game is borderline abusing psychologic flaws to force people to slowly deplete their wallets, but it's a gray area since you could say nobody is forcing you to play the game or pay for it. The fake 5-star rank however, is downright wrong and just reinforces EA image as a terrible company.
