When I played resistance on PS3 I could play it clearly and well as well as with GTA 4 but when I tried a demo of devil may cry 4 and call of duty 4 original CD the screen goes up and down and its really hard to play lol… cant even read what words are written in it like New game options and etc

Whenever I save my GTA4 game, and it says "Saving" - I go back into it after shutting the game off and I'm back in the same spot I was before - like it didn't save. I'll do some missions, change my clothes - but it always throws me back in the same spot as if it doesn't save. Any fixs to this?

i dont have a ps3 the only reason is cause their are 5 people that live with me. my dad and my three sisters. they are teens and my dad has to spread the money around and i guess it wouldnt be fair to get me a ps3 and them nothing as expensive. but any ways thats why i dont have one and i dout he would buy me the game cause when games were only 50 dollars he used to trip about that…but is there a way you can download gta 4 to your computer?
