I really liked Red Faction: Guerrilla. It’s sort of a cross between a straightforward third-person shooter (Gears of War, Lost Planet, etc.) and a sandbox game (Grand Theft Auto III). You play the role of what I would call a
terrorist revolutionary, fighting to rid Mars (your new home) of the evil Empire. This basically has you running around and removing evil ‘influence’ from various areas of the world by blowing stuff up. It’s like if the guys from Star Wars solved all of their problems by not just blowing up the Death Star but also by blowing up anything vaguely related to the Empire.
What you blow up is more or less up to you. There are both low and high priority targets that you can take out at your leisure as well as loads of missions to further the story. Red Faction comes equipped with what they call the Geo Mod engine which basically means damn near anything in the entire game can be destroyed. This is an awesome feature that I think many more games should adopt. It also makes for some ridiculous and satisfactory explosions. Want to bring down that skyscraper with a hammer? Yeah you can do that, but it might not be as quick as using, say, your rocket launcher.
