So as I said in my review of
Mafia II, 90% of the time you are either driving or shooting. Well
Jimmy's Vendetta is 100% driving and shooting. With a time limit. And high scores? The entire package feels very confusing as a pitch. Take the most tedious parts of
Mafia II, add an underdeveloped backstory, throw in an arbitrary time limit, post the scores to a leaderboard and call it a day. This really is the worst example of after-thought development that the single player story proves it is better than. I honestly expected more.
For the sake of describing the score system to those that are still interested, you are basically graded on two criteria: time and style. For every person you kill in quick succession, you add a multiplier to the total score. Driving fast or drifting around corners also increases the overall score and to "claim" your high score once the mission is over, you have fight the time limit to reach a checkpoint that seems as though it was placed at a random location away from the mission. That is literally all there is to do outside of the main mission objectives.
