The Grove
This is easily my favorite spot in any GTA game, this place is the heart of the Grove street family and your starting point in the game.
Maybe it's cause i played San andreas alot but this spot for some reason to me is very memorable. i still remember where the streets lead to and how the gym is close by, it's layout is ingrained in my head.
See that orange glow? San andreas uses that tone alot throughout the game and personally i really like it.
the lightening and weather is different in every section of the game, honestly, San andreas is probably the most innovative game of the franchise because it set the precedent for the future of the franchise.
Now every Gta has implented a stat system and a character customization system, oh, also, this game has the best soundtrack of any Gta game.
