Although i have never beat any of the GTA games my personal favorite is GTA 4. The reason for that is I would take a boat onto the water where a lot of other boats passed on by. I would then shoot a rocket with my rocket launcher underneath the water by the boats passing by so the passengers are launched off the boat. Next I would shoot another rocket underneath the swimmers and try to get them to land on my boat. The first time I succeeded one landed right next to me on a seat, which made it more remember-able.
