In Morrowind, apart from an unfortunate misunderstanding over an apple, my only crime was being a stranger in town yet I was continually greeted with the most virulent, and humorous, string of insults I've ever experienced in a game. From the simple N'wah through the terrifying 'We're watching you scum' to the brilliantly delivered and dripping in sarcasm 'Oh, how nice, a tourist'. Certainly added to the atmosphere, didn't need a GUI to check my reputation either.
So, what do you think guys and girls, did sarcasm and insults help your game along or do happy people make for a happy day?
Edit: Yes, happy people will still say happy things, but should unhappy people be more obvious in showing their displeasure?
A little music while you ponder and as a thank you for reading the first post: http://www.youtube.com/watch?v=K3CHi_9sxj0
Honourable mention goes to: 'You look half dead. Here, let me finish the job' lol
