Its Much Better Then Liberty City Stories.
you can swim and there is alot of aircrafts and helicopters, and the must greatist thing you can drive a apache helicopter and fire missiles.
you can make a big business, drugs , robbery , prostitution , night club, and more.
If you dont have any GTA on psp and you are thinking whitch one wanna buy, i recommend this one the vice city stories.
and if you wanna know the different between vice city and liberty city, you have to find my review in liberty city stories and you can compare them.
its enough to know that liberty city you cant swim and there is no aircraft or helicopters and the vice city you can swim and there alot kind of helicopter and aircraft.
