San Andreas can hold it's own against pretty much any game ever made on pure fun. I remember playing it when it first came out, it just blew my mind. Bolting down the highway in a stolen cadilacc, the cops on my heels, with Free Bird blasting out of the speakers. Simply legendary.
Something about the games you used to play when you were younger is special. I never get the same thrill of playing a video game than i had while being a kid/teenager. Crazy how San Andreas seemed so surreal back in the day and now were playing games like Skyrim, expecting it to be what it is.
