Fun as hell, but quite a bit rough around the edges. The game is littered with bugs. People disappearing, people not reacting to other people getting killed around them, no reaction from pedestrians when you use the tazer gun on them while they're on a motorcycle, you can't stop and stand still or crouch on a lot of the stairways leading to buildings because you'll slide to the bottom of them like a freakin' slip and slide (you have to run or walk all the way up, can't stop mid-way), there was a ramp on a rooftop I couldn't jump off of because the roadblocks made my car stop (like it was hitting a brick wall), even though I had already tipped them over.. and apparently there's a restaurant called "Kanto" that you are completely untouchable in because I've been killing people in there for a good ten minutes with a four star wanted level and not one cop has stepped inside the building..
But despite it all, it's amazingly fun.
