In this case you don't agree with me?
Most of GTA fanatics knows (it's a fact) that GTA San Andreas is > (superior) than GTA IV.
You can train your character (changing musculature)
Good story. Simpathetic Character CJ!!! He was awesome and his so does his "gang".
You can drive a lot of airplanes
You have TONS of great clothes
You can work as taxi driver
You can play in casino
Overall of cars variety is much better than GTA IV.
You can do extra-fun missions or things like Triatlon, Bycicle races, etc.
Soundtrack is HELL better.
Install and play - no need any patch
You can join a gang and attack other gangs.
You need to install a lot of patches to make it run properly. With my rig (and no patches I ran at 10fps), Patches 30-50 FPS. Really stock game is horrible built.
You can travel by train/taxi.
If I remember more I will post here.
