America's Army has a parental language filter that substitutes **** asterisks for the words deemed foul. I like that when my kids are playing. It's not more offensive than wtf.
An interesting feature is that with or without the language filter America's Army will automatically substitute a phrase. For example, "camper" becomes "person using tactics".
The same feature in Aces High might be interesting:
Dweeb = dead man flying
Vulch = death by stupidity
HO = death by stupidity, too.
HONK!
