(please note the non-existing sarcasm, he sayz it like he means it.)
I actually was shocked by that ending (I played that game as well). But honestly, I think it's one of the best video game endings ever. It brings up the idea to the player about how the real world could work, which of course is exactly how the real world works. The actual game was your typical naive/unrealistic good guys vs bad guys, and the game put you "on the inside" and into the action totally convinced that you know who the good guys are. So when the ending hit, I'm sure it surprised/shocked almost everyone who saw it, that despite being "on the inside" and "part of the team", you were a complete tool, completely and totally fooled about the real nature of the organization you work for. What you think is the good guys were actually funding, sponsoring, and creating the terrorists for reasons very well articulated.
I think it's a clever way to bring up this idea to the player, to hopefully make some of them think and wonder if something like that may be happening in real life. I don't think it was put there to make you excited about being part of the evil organization that creates/sponsors terrorism which results in totalitarian control over the population, with you as part of the "enforcement team". The player was convinced he was liberating people and part of the good guys, so I think it was in fact intended to shock the player and make him NOT want to be part of something that turns out to be the exact opposite of what the player was convinced it was. At least that's my impression, and so I thought that was clever.
The fact that this very concept could be presented to a large gaming audience without them knowing what's coming, surprised me. The fact that everything seemed "right/good" and "as it seems" and you thought you were "on the inside" and had all the answers to what was going on, and then to be shocked that you were nothing but a pawn for the very evil you thought you were fighting, I think it will have a positive result of making people at the very least aware of the possibility/idea that something like this could actually work, that all may not be as it seems in the real world as well. I dunno, I may be wrong about the effect of this, but these are the thoughts I had.
That whole time seeing that giant tower in the middle of the map, those "all seeing eye lasers" shining all around the world, all I could think about was how obviously this is a police state under guise of something else. So the ending was a pleasant surprise, that the illusion that the rest of the game was supporting was broken rather hastily.
