I'll have to mirror (Ha, geddit?) Mirror's Edge. I had no idea what was going on, then I got a slight idea, then it finished. If anything, its a feat that they actually managed to produce what is seen as an anticlimax to a story most people had given up on by that point anyway.
As for Gears of War 2, I actually thought it had a rather neat conclusion. What better way to end an epic story arc than with AN EXPLOSIVE DINOSAUR BEING BLOWN UP BY MULTIPLE SPACE LASERS. Gameplay-wise, it's lacking, sure, but RAAM was hardly an innovation on that front.
I'd rather a story concluded with whizz-pow-bang lasers than a twenty second boss-fight.
