As this is an MMO (no matter what the "official" description claims -- the facts are that while each server is limited to around sixteen of your friends or strangers, the game itself is incredibly huge in terms of the number of players, and thanks to the open-world architecture with which it was planned and built, it offers limitless Expansion (which is sort of the point) making it about as MMO as you can get and not be an MMO!
Being as it is what it is, the reason that we ended up creating this Reference Section was so that we could include information by sub-section that relates to the game but also so that we could include information that while it relates to the game series, does not necessarily relate to GTAO...
With that in mind you should expect to find three types of subsection here: GTAO Game-Specific reference sections, GTA Series specific sections, and finally, general interest information (for example the Aircraft Livery Page) that provides you with useful information that is oriented towards the scratching of information itches.
Thanks for taking the time to read this!
