It's a fun game but it feels half done. It still needed some work before releasing it, the campaign mode is mostly fun but 2 of the race types needed more work. The Drift Master races are ridiculous, with insanely high points you must gain to beat the race. The other race type that needed more work is the Waypoint, it's fine how it is but it needs a couple tweaks, there should be more than an arrow to guide you to the next checkpoint and the map should have shown the intended route you should take.
The other races are fun and I enjoy them, which are 1, Quick Race, 2, Time Attack, which is your classic race against the clock, 3, Elimination race, and 4, Boss Race. The soundtrack is fine but Unleashed 1 has a better soundtrack. The livery editor is cool, it works, but I wish Milestone just re-used the livery editor from Unleashed 1. I have not played with the track builder so I can not speak on that. I much prefer Unleashed 1 over Turbocharged because I find Unleashed 1 a lot more fun. I feel like I should say this again but Turbocharged is fun, I enjoy it but it needed some more work done.
