The non-playER characters (unless non-playing characters are some thing I didn't know existed XD) always play, just now it seems we need to count AI as player whereas previously only humans were counted as player XD
Hm now I wonder how an AI would go in a roleplaying game, and if we would get mad at each other.
I might have invented it ;D
Yes, this is my point and, they might seem more human than some of the humans these days :)
