Actually, that was one of the first things I tried. I enjoyed it in San Andreas, when you could just dive underwater, it also helped when you had a wanted level, there were times you could swim, and go underwater as long as the air held out. I am VERY happy to read that GTA5 has much of the same mechanics as S.A. had, in the above post. As much as i loved GTA4, I really wish that it had some of the same mechanics that S.A. did. Mostly, because I really got to like Niko's character. I did not think I would like him at first, but after I played a bit, I really got attached to him. I have to say one thing about the Rockstar Design team: They really know how to design a character that you get attached to. and in games with this type of theme? Yeah, that counts for something. I'd love a cross over though. I would really like to see Cash from Manhunt enter as a character in GTA...that would be SO COOL!!!!
