So i've been playing "The Crew - Calling All Units" for a few months now and it's fab.
You start off with one car and a race that seems too hard to actually win, but with a little practice and a bit of driving around the area picking up car upgrades, it becomes easier. The best way to get your car upgraded and to pick up a bit of cash is to find yourself an easy jump and keep doing the same jump over and over to pick up parts for your car.
Once you're a bit further into the game, you start to pick up more cars and are in the position to join in the online PVP events and "The Summit". Doing these player verses player events will get you more money and the opportunity of more cars.
The police chases are well worth getting involved in. Give them a go, they are brill.
