SA City was conducive for hang-out and roleplay since there were no hazards inside the map and it was fairly large and wide open. That's also why nobody else likes it. It's basically an expanse of nothingness, with completely barren fields that offer nothing to do -- no rings to collect, no obstacles to avoid, few activities or gimmicks or anything. The one redeeming thing that can be said about the map is that it is, in fact, a city, and so the map is fairly big and easy to get lost in... not that it matters, since the bare-bones architecture makes exploring those areas really unappealing anyway.
