Waste of $20....Power-ups have to be the stupidest thing NFS could have done.No nitrous like the old games.
1) Nitrous is a power-up not a bar that you could use at your will. When you use all your nitrous power-up you have to spend money to get more or get it at the reward card menu(it very unlikely to get a nitrous power-up this way).
2) Power-ups.....it feels like a little kids game. The computers use the most annoying power-up the traffic magnet. All the traffic moves in to your way. This makes going from 8th to 1st really easy. Then there's slingshot. A simple way to make you move from 3rd to 1st very easily. There's a lot more of them but I'm not naming them all.
3) No skill is needed.(look at number 2 for the reason).
4) The level cap for free users. Level 10 doesn't let you do much. You get let behind in the world because most people buy the starter pack. The car you start with is the best you can get at level 10.
5) No customization body kit and rims wise. Pretty much you can pick from 3 different packs of body kits and rims. The packs give you one set of rims and a body kit and a performance boost. Yep you don't pick and engine or tranny or tires. The paint job that you do is about all the customization that you can do.
As for good stuff there isn't really any thing. I wish i hadn't spent $20 on this game.
