"Is there anyone who isn't a complete asshole in multiplayer?"
I often ask myself that question multiple times when I turn on GTA to play online.
However, there are always cool people. The key is, unfortunately, getting killed many times before finding those cool people. I found 3 people yesterday, all in different sessions, who were cool. They all added me as a friend, and we teamed up and had a blast, and not one of us had a mic. It's really an awesome thing when you find cool people. Admittedly, the first 2 new friends I found yesterday were because we rolled up on each other, each driving the same type of personal vehicle. It was like we clicked instantly, got out to examine each other's paint-jobs and mods, and then drove around the map together and fuçking around. It was great.
Hold on to these guys!!
