The game suffers from a crazy amount of pop-ins, the framerate crashes all the time, there are too many bugs and glitches to name. There are no planes, the heli's handle like shit, they take away a crazy amount of cash when you die, you are forced to use weapon and health cheats non-stop, the cops come after you all the time, even if you do nothing.
Other times i have shot a gun off in the middle of nowhere and before i know it there are 5 cop cars and a heli flying over head. I played yesterday for 20mins and received 3 phone calls and 2 text messages. The mini games are stupid, they took away most of the great features GTA:SA had. If you enter the airport you receive 4-5 stars.
I have tripped over the sidewalk and received damage, the fighting system is broken, the camera system is broken, ever try jumping out of a boat, you will fall down about 5 times and lose about half of your heath. I have walked around for minutes on end and have not seen a single person or car, this happens all the time. I have seen people and cars appear right infront of me.
The game loses all its colour sometimes, its like playing a black and white game. You have no space for cars, good cars never appear anywhere in the game, i'm still finding cars that i have never seen before. All the missions were the same, the hiding system is useless, i never used it for any of the missions. Stupid AI, sometimes you die from falls and sometimes you don't, the map is too small.
Plus the game is not fun to play.
