UPDATE: well I'm playing this game from a long time now so it's time to a longer rating.
first of all the graphics is still beautiful and the voicelines are still amazing! The storyline is good, but the game update is slow so if you already read the last chapter you have to a wait a long time for the next one. In this time there are little or bigger events but they're all the same so in the end they become boring.
the cards are really a piece of beauty, but getting them? if you don't spend money on the game it's a nightmare. Or not a nightmare but it's really hard. I know the developers need to get some money from the game, but getting invitations only by money or really, I repeat really hard work takes a lot of time and effort. I'm a college student and I merely have a little time playing this game so.. but in the end I can't just stop playing it because I have way too high level in the game (I'm on lvl 74) and I don't want to lose it.
so overall from lvl 70 the game without new chapters and with only a few events become a bit boring (for me at least).
