The two that come to my mind are : Carmaggeddon ( a massive 3.71 mb if audio, bout 200 diffrent shouts screams car noises and cars hitting people/zombies)
and the original GTA , which only had about 6 audio files but they were the intro gansgsta speechs
So what have you enjoyed? i reckon the halflife series has some good audio folders
i was going to suggest swaps but i think that may break forum/ethichal rules
