Awful and a waste of time
The graphics:
They are horrible. There is nothing on the streets, textures are blurry, geometry details are low and objects look blurry. The view distance isn't high.
Sound:
Cool 70's tunes? No. There are only a few songs in the game and they repeat all the time. Nothing to compare with GTA.
Gameplay:
It feels like a GTA wannabe. AI is dumb, there is nothing on the streets, not much cars, bad controls and boring, short missions. You will have some fun in free roam, maybe 45 minutes. Cops lose sight when you change the car when they don't see you. That is nice, BUT: They can see through walls sometimes. It makes that feature useless.
On-foot controls are bad and shooting feels bad too.
Overall:
You can beat the game in 2 hours. It is horrible and you will have bad feelings, that you wasted your money on it. Pick up GTA: Liberty City Stories and leave this junk in the stores. Not even worth to get for free.
