The highest level on GTA III was 5,000! I think that Rockstar realised before they put Vice City out that there is an awful lot of seriously hardcore people who hit 5,000 within a few weeks and decided to put the highest level up to absurd levels to make it a serious challenge.
And several people even on this small forum managed to hit 1,000,000. That's why I thought when I saw King of San Andreas as a higher level than Godfather that they might have gone silly and made it 2,000,000 or more.
I've come across a couple of lists similar to mine on other forums, but it looks like some of them made the same mistakes I did and misread the list so put "Four Star" and "General" as different levels. But they also included numbers for them which makes me think that a lot of the numbers floating around the internet are bull****. It looks like they just stuck numbers beside incorrect level name to make it look like either they'd reached those levels themselves or to make it look like they knew what they were talking about.
I trust the regulars here when they hit higher levels more than I'd trust a list posted by some stranger on a forum where people are still putting up posts and threasd like "I killed Bigfoot with a rocket launcher today!".
