This is cool, FBA definitely have a lot of potential for their affordability and reach. It's nice to see someone taking some strong initiative to advertise & spread awareness, kudos tk!
We should definitely collect as much data as possible while the ads are running to get a more accurate picture of ROI; the numbers can look pretty good (x impressions, y clicks) but we need to figure out how many war2combat downloads that actually translates into -- I'll see if I can set up analytics to track the behavior of traffic referred from FB. Likewise, even if someone does download it doesn't necessarily make them a new long term player, but it's a starting point. Have you done any split testing of multiple ad layouts to see what gets better results?
