The only drawbacks are that the games is pretty linear and there is no multiplayer component. You get instructions, complete the task, and move to the next job. I personally prefer this to the more open ended games like Grand Theft Auto, Assassin's Creed, and Far Cry 2. There's not much replayability-just 3 difficulty levels and a fourth is unlocked after completing the games. I played on medium, which was just about right. I never got frustrated, but the boss battles were a tad too easy. I put in about 14 hours total-not bad. This is one of the best games I've played on the 360.
