I really like this game. Sometimes I don't like open world games because then the individual missions don't seem to be as tightly designed to show you new things as you progress through the game, but I don't find that to be a problem here. I know it's not everybody's favorite, but I actually like hunting around the world looking for the different collectibles. In the course of figuring out how to reach certain areas, you end up learning the space within the city very well, and it's a cool feeling of discovery. If you're not interested in 100%-ing the game, then you don't have to worry about stopping to look for stuff everywhere. However, I like the collectible hunt. It's not just a mundane scan of the environment. You have to examine the structures and figure out how to reach every nook and cranny, and that's where the fun lies. Overall, I think this is a good sequel. Because the mechanics are very similar to the original game (just a few new moves), it doesn't feel as fresh and innovative as the first game did. However, I would still say that there's really only one other game like it, which is the first Mirror's Edge. So this is still a fairly unique game. Some people have criticized the story. Yeah, it's a bit cliched, predictable, and it does take itself quite seriously, but within it's own universe, I still think it was interesting to follow along. If you like the game, there's a lot to do. However, if you're not interested in scouring the map or perfecting runs, you'll get less mileage out of the game. You'll still have a decent campaign though, on par with the length and quality of any good modern single player game these days.
