Take an open world game with lots of good explosions and gameplay, add character progression and RPG elements, stir liberally and you get Crackdown. This is a great game that I continue to come back to every few months or so. It's easy to pick up and play, and jumping over and around buildings is fun.
I'm not a wordsmith, so all I can say is that this game is definitely worth the money and will provide several hours of fun.
