Huge update on the size of San Andreas on Gamespot today. Here are a couple of notes to give you some ideas.
In Vinewood:
- Keep an eye out for such landmarks as the Cathay Theater, the walk of fame, and the famous Vinewood sign, nestled high up in the Vinewood hills.
- You can head up into those hills to find the truly impressive mansions and estates of the Vinewood elite.
In Rodeo:
- Think lots of trendy architecture and beautiful plastic people, and you're thinking the neighborhood of Rodeo.
(It's pretty much where they rich and famous live.)
Downtown:
- You'll be able to zip into and out of the downtown area with ease by riding the Brown Streak railroad, Los Santos' public transportation line.
(Pretty much where everything is happening. Businesses all around and skylines are covered with skyscrapers)
Quick amazing screenshot time...

That, my friends, is part of the freeway.
On the topic of streets, each street in San Andreas has a name. There will street signs located throughout that gives you directions to actual building addresses.
Tattooes:
- In keeping with the gangsta rap spirit of the storyline and your surroundings, the tattoos that will be available will be of the gangs-guns-and-girls variety.
- Looks like you just get to chose from included inks but I wouldn't doubt seeing letters as some of them.
Gang Land:
- If you're being chased by the police or by enemy gang members, you can try to lure them onto your home turf and let members of your own gang come to your aid, bailing you out of what would otherwise be a rough situation.
- If you stray into the turf of a rival gang, whether in a car or on foot, you will be attacked, and not even all at once. Gangs will use varying tactics to take you out, by splitting up, sending ahead advance attackers, and using other wily maneuvers.
- You'll see guys greeting each other, talking on street corners, and flashing gang symbols. These are key signs you'll need to watch for.
Ok now this part I'm just going to copy the whole thing because it's amazing...
- Unlike in Liberty City and Vice City, where every car is apparently new right off the lot, the cars of San Andreas aren't always in the best of shape. The rides you'll pick up, even new ones, will get dirty simply from constant use--you'll see dirt showing up around the wheel wells, on the windshield, near impact points after a fender bender, and in other common trouble spots. If you want to keep riding around in style, keep a look out for carwashes that you can use to maintain the sleek look of your vehicle.
Some of the cars you jack will sport some pretty serious damage, too--look for everything from broken windows to loose bumpers and even bullet-riddled doors. Apparently, some of these cars have already seen a good deal of action.
That's pretty much the major points of the article, you can go and read it for the other little bits but I covered most of it I believe. Here are some of the new pictures as well. And again, credit goes to Gamespot.
This is the train station.
CHECK THAT OUT...lisence plate numbers.
