you play too much fiesta when:
you seperate your IRL friends into Fiesta players, and non fiesta players
Your msn list is seperated into Pro and Noobs
You try to move with W A S D and the right click
You think everyone wearing purple clothes is a mage
You run around the city trying to buff people
You go out, get bored, and start to pretend everything around you is a map from fiesta
( apparently the Yarra river is now CP xD)
