*V is much better than SA. The latter is one of the overrated GTA games.
No surprise there coming from a certified San Andreas hater. You are one of those certain guys on here who are just mad that SA is so overwhelmingly popular with GTA fans, and still is preferred over newer GTAs like your dearly, beloved Niko and GTA IV. But it's all good, you are entitled to your personal opinion.
* I'm not joking at all bro. GTA IV actually was better in certain areas than GTA V. For starters, IV has a better storyline and much more interesting and intriguing set of non-protagonist characters. IV has better immersion and interaction with it's city environment, it actually more accessible interiors than Los Santos in V. In my view, I preferred the gunshot sounds of IV to V. V is better, just not by much, that's just my view.
* Vice City is my favorite GTA and I think it's slightly better than SA, but only just. My favorite GTA protagonist is Tommy Vercetti, and I just loved the whole Miami style-setting, 1980s vibe, it's then-new features were groundbreaking and the storyline was brilliant ALL the way through. It just an all-round excellent game. SA was very similar to VC in all aspects, apart from the storyline which was good for most part, but got a bit stale and silly in certain areas. But make no mistake, I have a massive amount of admiration and respect for SA, it's easily my second favorite GTA.
