While these traits create a slightly interesting storyline, the storyline ultimately fails. Partly due to very little character development outside of the videos and audio logs, and partly due to the stale repetition of its missions.
Now if splash damage decided to "man-up" the game with some more action, making the resistance more edgy with less of a concern for the security, but at the same time making the security more totalitarian, if it was kept balanced it would be more interesting. However it could be said that a in-balence could also spark a more interesting story. Make the security totalitarian but have the resistance be all out fanatics. That may seem cliche but it could be achieved with success and interest.
However the edgier you make a game the more controversy it causes. If Brink went for a hardcoe M rating, with exploding heads and everything( Which would require the graphics to be boosted from very poor to good) then it would attract controversy, which is always interesting. Just like that experienced by the game inspired by the failed military mission in Falajua.
The problem is that splash damage isn't trying to appease a hardcoe audience(which are the only ones who want its type of customization and complex game play). They even changed the name of the "Comms Hack" ability because it sounded too much like torture and Brink(paraphrasing from Paul Wedgewood who isn't the right person to lead a game build like this in the first place) " isn't trying to build a visceral game" So they didn't need to worry about problems caused by what in essence is terrorism, but losing the possibility of a core audience who smirks at "T" games
Changing brink to be more edgy would fix some of its major flaws of poor graphics by requiring more lifelike damage and guns but also the lack of spice in the story which i could tell from the beginning would be a them vs us mentality with maybe one or two people in each group who "feel" for the other side. Instead of putting real emotion into the game they marketed it to the little kiddies, because so much money was lost in development, I would blame the head of the project for that.
TL;DR
Brink would be better if it was made for hardcoe gamers with more intense visceral ideology. Incoperating better graphics to pull it off.
In the end a lot of potential, but none of it was realized.
