The note on IP and producing an official piece of work is very much welcome, Crimsondude. I would actually be interested into contributing minor parts or team up with someone. NO and the CAS really interest me and as mentioned somewhere else, I'm a historian. So telling a story and reading into material is not far from my daily work.

Thanks for the kind words and the input. I fency Google Streetview, but it only works up to a certain point. The ideas about Humanis-specific neighborhoods is perfect. I will need a show down zone at the end of the season and Bucktown is at the exactly right spot, because the Elmwood combat zone is close by and Humanis can send its thugs in. I had Westwego in mind as basically the human version of orkish Bridge City. Thus far it's no combat zone, because humans dominate it and certain gangs (Humanis, the mob) keep it "safe" (aka defend their slice of pie). But that all might change as soon as the National Guard start to plow through the insurgents.
I also noticed Michoud and the NASA facility, eventually coming up with similiar ideas as you did. It's Ares territory, but several tenants rented into it, including a trid-studio (I read about that on today's Wikipedia). Ares is not especially mentioned in previous publications on NO, the focus seems to be rather on biotech and petro-chemicals, which led me into designing the Shiawase vs. Saeder-Krupp plot. It also fits into the group's background story, as they fled their former life as Fuchi corpsec before the crush, just to hide out in NO. Little did they know...
Due to that, I kept Ares out of my game thus far. I guess, I will run is as some form of "you've been transfered to Alaska" for Ares CAS employees. A site that is large, but understaffed, underappreciated and very much forgotten by the higher ups. The major sites of Ares in the CAS should be Atlanta and Space City (AL), I think, so once more NO drew the straw on that one.
Last but not least I thought about NO being a tourist attraction and how it would make sense to the city government to make it appear shiny and new, but don't have to pay for it. Preferably while creating permanent jobs that can be given to loyal servants of the powers to be. I found inspiration in the new Stolen Souls description of NYC: The easiest way to make your shopping mile look like a tourist attracting, romanticistic "re-creation of former times" is by signing a law that makes every shop owner put so many "historically accurate" AROs in front of and into his shop that no-one can see the demise. The joint venture of the New Orleans Police Services, the big corps and city hall is called NOMOS (an acronym New Orleans Matrix Operation Services and Greek for "law") and enacts matrix protocols, security and "a common design for the augmented reality of our historical city that guarantees a maximum of fun, safety and authentic feeling to our guests and friends from all over the world". In short, every house, shop and street is programed to look like a reenactment fantasy of the 19th century in AR, while in real life it might just look like, well 2005 all over. Of course corps and their buildings, hosts etc. can buy themselves free of those regulations for the sake of "maintaining their corporate identity". Gosh, I love the possiblities of a corrupt dystopia.

As for Royal Dutch Shell: They seem to have merged into "Regulus Joint Industries" a British-Dutch megacorp (AA). Its covered in Corporate Enclaves (116-118) and Shadows of Europe (28, 211, 213) as well as numerous German publications (mostly translations of the above).
