Its some real $$$ grab mmo, I believe. You get like 5 mins of real game time and have to pay real money should you want to do anything else worth anything.
I can't believe it made it so far through the voting, and has such a high score for such a terrible game. The mechanics are simple enough. And the game play isn't hard. Its the fact that everything that lacks from the game requires real money.
I think you might be thinking of some other game. I only played it for a few minutes before I got bored and decided it was a bad game, so I'm no expert. But I don't think that all those people who like it payed money. Like I said: I'm no expert, so you could be right.
