SA blew over VC because of that image blur effect they used to simulate speed. which took games backwards if you ask me.
yes you didn't have load screens when you changed location but the fake speed effect sucked in SA big time, its was no more then a cheat for proper game coding.
in VC you actualy went fast, they didn't just blur the image, drop frames and screw with your control inputs to make you think your going fast.
Though SA did have its perks, the speed thing kills it for me.
