Please Sir. I beg of you. We all beg of you. Make another, With multiple car types, customizable cars, an easier to handle Trap to Road making system (or whatever). If you make a bigger and better version of this, It will definitely win money, I'd vote for it. And if you don't make another one, then someone else will, With blackjack and hookers.
I feel that you should add a talent that increases the range that your weapons can reach, Possibly making the Uzi less of a suicide weapon. And Adding another talent tree might also be an interesting thought.
