Just got it.....played only for about 45 minutes, all I can say is that I can\'t believe the language in this game, and that parents are buying this for their children.  The game seems really good to me, but I just can\'t get over the language.  Personally I like it like that, but i just think that it sends a bad message across to kids playing the game

This game is **** HARD!!!!!!!!!!!!!!!  IN all ways. Thanx Wah for your attempted help but those are the same codes as GTA:VC and will corrupt one\'s game just as it did for VC. They were kept the same for a reason and one only. Programmers get lazy
 I have yet to open any other "city" and have been playin\' like mad. I am not all that bummed though as there is freakin\' plenty to do in Los Santos. Wow this game is very realistic in it\'s portrayal of L.A. pre OJ riots. Cops are **** everywhere and **** @ every chance. Gang wars, burglary, it\'s just silly.

Finally finished the storyline and have only completed 73.12% of the entire game. I have logged only 55 hours of time in completing the story. One of the best storylines in a videogame EVER!!! Awesome ending  I\'ll tell you that.

i\'m about halfway through the san fierro missions and i absolutely love this game.  i wish i had more time to play it, but between work, my band and trying to get my recording studio up and running, i barely have time to zip up my fly after i take a leak.

yeah driving school is driving me nuts.  do you need to complete driving school to progress in the story?  if not i might put it off for a little while.

yet another opportunity to procrastinate on something.  beautiful.
