I admire the combat system in Mirror's Edge because of how difficult it was to master. The game is not a standard shooter in which you mow down an endless horde of less than intelligent enemies. The enemies in Mirror's Edge strategize, form counter attacks, and are nearly impossible to sneak up on. As a "runner" you are not compelled to charge head first into bottle with guns blazing either. You instead must master an array of well timed disarms and aerial maneuvers to outlast the enemy.
Finally, the game's gender neutrality is refreshing. The player controls a female character who is strong, swift, and interesting. She is interesting in the sense that she has a unique back story, not because she contains hypersexualized qualities. The strong female role combined with a combat system that is not overly violent make for an experience that girls can enjoy just as much as boys.
The beautiful art style, non traditional combat system, and respectful use of female characters in Mirror's Edge create one fun and memorable game.
