San Andreas all the way. It blew my mind when I saw how far the map went, and how diverse the environment is. It's not just one big city. It's 3 big cities, a countryside, a desert, and multiple small towns. It was an amazing ride all the way until the end, so many awesome moments and I still play the game to this day. The music choices were excellent too. Perfect for driving cars, planes, boats, hoverboards, etc.My favorite childhood game is GTA San Andreas. The game was just too good when I first played it.
