A perfect game would have great realism and graphics while also having great vibe and options like GTA San Andreas.
Then whichever will be your favorite depends on what is important to you. Personally my favorite GTA game was Vice city followed by San Andreas but I also love the realism on GTA4. I just care about the vibe more. It was so fun to play Vice City back in the days. GTA4 made me "wow" for a moment but then I really got bored of it quite fast.
If I had Vice City/ San Andreas with GTA4 realism and graphics (or maybe superior graphics since GTA4 seems outdated at times) that would be something awesome.
