My one on one interactions with people in game nowadays are about the same today as they were in 2002. Some people are kind, some are wankers.
What to me has changed is the overall bond between players. By that I mean, players working together to overcome the challenges of the game. Helping out strangers for no reason other than to be nice. Generosity to newbies. Buffing passers by. That sort of thing.
I see less of that. But that's just my own experience.
