Fun always matters. But the thrill of competition shouldn't get in the way of fun. I for one have been through both of those (tekken arcade scene), the greed, the ego, the will to win, it just eats you up lol, although I just usually get it if I don't like the player, or during team battles. But for everything else, especially casuals, fun should come first, playing a guy who just plays to win takes ALL the fun out of it. Cheap tactics and all. That's prolly the one thing I hate during casuals. But hey what can we do, there are people who just play like that. Can't do nothing about it.

P.S. sometimes it sucks when you main a character because he's your favorite, then he turns up as top tier, and you end up as a bandwagoner. massive LOL.
