It has to do with Vice City, and the Lawrence Taylor Character. I can't remember if it precedes Vice City, or happens after Vice City.
There are a few hints about it being San Andreas. I wanted Sin City, and I was disappointed. But they stuck to the script. What the fuck is in CA?
Anyways, at the airport in Vice City, around it, anyways, there is a warehouse (actually closer to the docks) and a crate or two has writing with the words San Andreas etched on it. Question is, was it to San Andreas, or from San Andreas? Also, Lawrence Taylor's character, who owned the car dealership, did interviews on the radio station. Mentioned playing a game in San Andreas with two broken legs. Denotes past tense, so I figure this might take place in the 70s, early 80s. BUT, when Tommy Vercetti buys the dealership, LT says he is coming out of retirement. SO...The game could just as well be taking place in the late 80s
Best guess? late 70s to late 80s
