Halo Gamerscore

Hi, I would like help to get a clear idea of the list of games that count towards the Halo Gamerscore in this site. Also the ones that do not count as well, since is not specified anywhere, it is not clear, apart that Halo 2 for PC doesn’t count. What about Halo 5: Forge in Windows 10 or Halo Wars 2 for Windows 10 do they count?
Thank you for answering. :slight_smile:
