Lust, crushes, and desire are also part of life.
Gaming emulates life, albeit life of a more colorful variety.
To quote the vernacular, love is a many splendored thing. To quote a once popular Gen-X song, love stinks. Role-playing can often breed emotions towards people, and love is a dangerous emotion to toy with. I'll assume that most people game with people they like, maybe they even game with friends. If people who like each other continue interacting with each other they eventually become friends, and there is a kind of love amongst friends.
