Well I've been playing "24/7 Freeroam-Buy this Server today..." alot and I find its more interesting than racing. I tried cops and robbers, but there was a couple of people who had a teleporation hack on and instead of cops vs. robbers, it ended up being cops vs. cops. So I stopped playing that.
Free Roaming, I enjoy killing other people and confusing them to death, I follow them around and ram them a couple of times and they get confused and start to run. I chase them until they blow up, it entertains me.
