If you look around Wikipedia, especially around articles concerning fictional entities, the detail of the entries is astounding at times. For example (because I'm currently on a Command and Conquer jones) check out the articles on the GDI and NOD factions:
http://en.wikipedia.org/wiki/Global_Defense_Initiative
http://en.wikipedia.org/wiki/Brotherhood_of_nod
Many of the items (albeit, could be fake) could only be derived from speculation or extensive research, as much of the information is not found in the games which feature GDI and NOD.
My question to you is this, does this represent to you, people who have
way too much spare time, or does it represent a true fanbase for a product or series?
Oh, and just for giggles, which is your favourite side, GDI or NOD? For me, its GDI all the way.
