I've been doing research on viral games for last few months. I was wondering how these games went viral so quickly. Take for Example Flappy bird. That game didn't have high end graphics, no levels or stages. Not even a storyline, just a simple tap and play game. It was in the appstore about 3 months before getting any heavy downloads, then BAM it goes viral. The developer never paid for marketing the game. From what I have found in my research is, social media was the key start. After youtube star PewDiePie did a video about it, Facebook users started making videos and posting scores then Vine and Instagram videos took it over the top. After that is hit the news on gaming sites which made it go more viral. Was PewDiePie the reason it went viral? or was it something else? So now I'm wondering can going viral like this be repeated? Is Social media really the key to success? Should we contact Youtubers and Viners to market our games instead of ad agencies? what are your thoughts?
