Very good but story not as interesting as gta-sa - read my full review
the missions are not as challenging as gta-sa. also i somehow liked the big and huge area of gta-sa.
u will not find and draw backs in the game as in sounds, or graphics, gameplay or any other thing, and on the first look u will really be impressed by the game. there is no harm in playing the game too as this is not bad at all. but oif u compare it with gta-sa and it loses its charm. theer was a lot to do in that game which this game lacks.
in this game they have mainly focussed on killing people. niko works as a hired through out the game which makes the game little boring after sometime as we dont have anything new to do.
