I'd like to add Mirror's Edge to this list.
Not that it wasn't a flawed game. The pacing of the gameplay could've been better ( when the point of the game is to run fast and leap from building to building, building up momentum as you go and elegantly chaining moves together, having to stop and figure out where you're going sort of sucks ). I think the main problem, at least for me, was that it tried to be something it wasn't. By giving you the ability to take weapons from your enemies, they slowed the game down further. Just taking away that would've made the game better, and definitely would've made the gun-toting enemies more threatening.
That said, the concept was fantastic. Most of the time it works, and when it works it's great. The story isn't all that, but the setting is great. They did such a good job of creating a beautiful anti-utopia. I mean, this is how I hope the future will look, all clean and bright with lots of glass. I guess I'd prefer if the world wasn't controlled by evil corporations, but ... it seems we're headed that way anyway, so whatever.
