I am planning (if you are cool with it) on making a gamestalker mod for recon-ng. The idea is that you give it a single name/tag (eg, lanmaster53, mubix, webbreacher) and it'll search all the gaming sites (eg, ea, xbox360live, steam...) for that name and then return what that person plays, who their friends are and other things about them (check out this one link I found while doing recon for this mod - http://www.xfire.com/profile/mubix#rig-info). This one is pretty cool recon about a person. Many people (at least hackers) use the same hacker name for their gaming (a la mubix).
This is a little outside the normal recon-ng "get info about hosts and get contact info of people". Wanted to propose it before I do it. Thoughts?
