Like you Dire, I never once emailed anyone about people flying past the enemy, nor did I complain to the developer. I simply called folks out for that kind of play in the game and left to do something else. I don't take the game seriously and don't for one second think its in any way real. Its a game and not worth getting upset about. There are lots of other games and activities out there that I personally enjoy so it is nothing to leave a game of df where people wont shoot the enemy and do something else. The game as it is currently designed doesn't play well when every red doesn't shoot at every blue, and vice versa. What happens when the only players left to play are all from the same squad? Oh, that would be a whole lot of fun.
Folks who believe a video game is somehow real, or get a sense of accomplishment or self worth from a video game need therapy in my opinion.
