I have fun when I'm playing in tournaments. I have fun when I do well in tournaments. I have fun when I don't do so well in a tournament but learned from my mistakes. I also have fun when I'm trying out new lists on casual game night and getting my butt kicked but learning a lot. I also have fun when I get to play an Epic game at a friend's birthday party.
If I'm playing X-Wing, then I'm having fun. The game just keeps on getting more fun.
Unless one player's dice (including my opponent's) are ice cold to the point of it being completely one-sided, then I don't have as much fun.
