In San Andreas, there are just too many to choose from. I love Las Vegas so being able to visit a fictionalized version is always fun. Despite a big chunk of the game's story being in Los Santos, I probably spent the most time in the desert, mostly due to the hardest mission known to video games, the dreaded Flight School. But, I enjoy the secretive Area 69 and visiting the old ghost town of Las Brujas, in the hope I might see some urban legend.
