Two points.

They're going to a level of detail far beyond summary. If someone wants to learn about the structure of UNATCO (for example) not only would Eidos like to sell you a game (they could use the money), there are many, many fansites who can speculate, offer analysis, compare Deus Ex to other works, and do all sorts of things Wikipedia, as an encyclopedia both can't and shouldn't.

As for the lists of various agents - I may later regret suggesting this - how would you feel about a "Trivial/Generic characters in Deus Ex" article, covering the robots, the generic MIBs, the soldiers, and so on? I'm not really happy about it, but it seems like a logical place to dump this sort of thing. -  (conspire | past ops)
