I would prefer a more tropical setting, be it Vice City, LA, Honolulu, somewhere in the Caribbean, New Orleans. I suppose a beach setting is the word I was going for. Havana, Cancun...
And if it happened to have a volcano thats constantly flowing lava, that'd be super cool, so I guess my vote is Hawaii!
We've already had a cold climate city, LC, so please, no Chicago, Detroit, Boston, Seattle, DC, etc.
As for time period, it really doesn't matter to me, though I do like the 80's for the music.
Was it just me, or did San Andreas not "feel" like the 90's? I thought they could've done a better job on the soundtrack. Felt more like the late 90's I guess, but without the boy bands
