body: I'm currently writing a companion to the popular game Overwatch, and have realized early into development that I don't want to put time into this and then find out I can't use it for legal reasons.
  
  
  My program will contain information that is copied from different sites and locations, including Overwatch itself, as well as several websites. I am fully willing and even eager to include the authors of the information, but I'm worried that Blizzard will try to murder me legally for attempting to use data from their game.
  
  
  It will not cost anything, and I will not make any money except for donations. How legal, if at all, is this?
