The goal of PCGamewiki is to have a page dedicated to every single PC game, and for that page to contain everything one would need to know in order for the game to 'up to date' and provide the best experience for that title. This would include 'how to' information such as:
-Latest patch or fan patch
-Mods that are considered essential
-Skip DRM methods
-Skip introduction videos and cutscenes
-Steam/digital distribution/retail differences
-Save game cloud sync and same game locations
-Borderless fullscreen windowed
-Console commands and cfg files
A good example article would be Titan Quest: Immortal Throne or Kingdoms of Amalur: Reckoning which contains information about all of the above.
