Total Immersion
the game takes virtually no time to get accustomed to except for the norm as far as controls. you simply drive to an intersection and start a race. i like that ability to unlock different versions of you unlocked cars to get supped up versions. i have to admit i do hate losing a race, and being dropped off immediatley where i am, but it forces me to drive around the town some more in order to get back to the start line. i helps you to learn the city.
online capability is the easiest i have seen. you can effortlessly switch between on and offline by one press of a button. automatically just jump into races/worlds/ challenges.
i can't wait for the expansion
