I'm banking now that that's where Rockstar is headed with this one. At least I hope.
(For the most part since I didn't know what to do with all the money I ended up earning.)
VC is worth the purchase just for the bikes. Racing from one end of the city to the other while pulling a wheelie is fun.
Still haven't played VC, but I'm thinking of getting an Xbox and if I did I would probably pick up the GTA pack.
Not particularly considering the original map had a gigantic red bridge crossing the harbour and areas like Richman (actually Richmond) and Sunrise (Sunset)...
As far as I can tell there isn't an actual city known as San Andreas. California does have the San Andreas faultline which runs pretty much the entire length of the state. Given how different Northern, Southern and Central California are from eachother it's difficult to say which California city inspired San Andreas.
