I dug Fallout because I was a way into the "Day after Disaster" sci-f books when I was a kid. So the idea of roaming the wastelands like Mad Max appeals to me. Listen for the subtleties in FA3. The supermarket is a lot of fun for that. Some of the audio reactions are a hoot.
But I did discover in GTA IV that if you do wheel spinning donuts long enough in the cars, the tires will blow up. The cars handle like shit on rims.
