And what we see here is exactly the same kinds of elements that we saw in Empires and Allies. So, we see again the points and we see again the levels. And if you look at this interface for points and levels in KEAS, it looks very similar to the one that we saw in Empires and Allies. I mean, graphically it's almost the identical thing on the screen and that's not by accident. Here KEAS is using a familiar structure that some of their players or participants may have seen and not only adopting those conceptual elements, but adopting some of the aesthetics of them as well. Similarly here are the quests that you go on, here's the social graph, seeing what your friends do, here are the avatars. The, the visual graphical representation of each participant here we also see rewards. If you do certain things in the game, you get more points, or you get other benefits. And down here you can't really see it on the screen but you see the label for it, badges. These devices that demarcate or represent a certain achievement in the game. So, there are exactly the same game elements in the KEAS service as in Empires and Allies but you can see there is a great deal over lap and a notion of elements. The notion that there are these regular design patterns is something that's common across games as well as gamified services.
