A couple of days ago a friend and I had the afternoon free so decided to meet up around his house for a friendly 1500pt 40K game. I was playing my Salamanders and he was playing Chaos Space Marines. The outcome of the game was a victory for my opponent but it was one of the best, if not the best, game of 40K I have ever had. What made this game so special? Simply, it was played for fun. Neither of us fielded a powerful list and we didn't go all out to win at all costs. In fact my opponent made a conscious decision that could have cost him the game but took that play because it was fun and made in-game sense.
It has made me wonder why more players don't play for the fun of the game, rather than to win at all costs? In my experience even if a player isn't a WAAC type, they still play very competitive. I think the game would be better if games were far more friendly and less competitive. Play for the fun of it rather than to crush your opponent.
