How can Cut The Rope be a "Russian Rip-off" of Angry Birds? They're completely different, unless we're counting the fact that they feel like solid and professionally developed games.
More power to them, they are filling a need that is generally unserviced by an English speaking hegemony. Yeah, there are some rip offs, but imitation of popular brands is nothing new.
Biglion screenshot is photoshopped. Anyone can confirm that by visiting <a href="http://biglion.ru/" rel="nofollow">http://biglion.ru/</a> and comparing it with the image in the article. It IS a groupon clone, but why lie?
