Zgyna’s edge is simple they put free games on the market through facebook and then analyze data from their users to create valuable new items that can create a profit for Zygna.
There first game introduced on facebook was a poker game. This game created a lot of buzz and then designers added virtual goods you could buy at the poker table.
I have bought backgrounds for xbox360 platform; one was a Nazi Zombie background that would show up when the system was started.
Being a business major I would have to decide on the choices driven by data. The data is what is keeping Zygna up to date on the market and the influence facebook users have on each other. While having an attractable design/game is important, it is useless without more people playing and collecting data is how that is accomplished.
