@Marky360 @1337hackz In my opinion GTA IV was a much better game overall. Nico Bellic as a character was much more interesting rather than a typical 'gangster.'
Much of San Andres's map felt inhabited and dull. Though I agree they should have kept most of the vehicles they had in SA.
I think the main reason why people prefer SA over IV is that they have the perception of "Old is Gold."
In other words, nostalgia plays a large factor in their preferences.
