I go to tournaments for friendly competition that actually has something at stake. The prizes are appreciable enough to want to win, but not so amazing that I feel bad if i don't rank well. It's not like you're playing for high-value prizes the way other games do.
Armada has a fantastically friendly, good-natured, and courteous tournament community in my, albeit limited, experience. From what I've heard from our veteran local players, that is common among most of the tournaments.
