A few quick searches didn't turn up a thread of this nature, so here it is, the dedicated Netrunner Flavor thread.
I like having discussions of this nature, not to mention that other people can see flavor and fluff that I miss, and I like seeing all the connections between different cards and the like.
For instance, looking at Big Brother the other day (don't ask me why, I don't know myself), I noticed for the first time that Chaos Theory is the child in the picture - I just never noticed Dinosaurus in her hand, and the robot thing covers the side of her head that's mostly shaved.
And if you read all of the text on The Twins, you might get a sense of Deja Vu...
But hearing about the different flavor stuff people like is interesting too, so everything flavor related that's actually on cards or in packs (like the paper that comes with packs/boxes), is all on the table.
A few of my favorite flavor things include Valencia (having a good-gal runner, in Anarch no less, is awesome), Kit (who continually reminds me of Technomancers from Shadowrun, interacting with the code in a strange new way), and Biotic Labor (who's flavor text is exactly I would expect from a mega-corp).
So, find any strange or new connections between cards, or have favorites you just like to talk about? Share it here.
For everyone that contributes, thanks for your time and effort.
