One fun thing about 4e is having to name all your monster types. For example, I wanted to have some 1st level Tieflings for the 1st level PC's to get into a brawl with. In older versions of D&D they would have been "First Level Tiefling Fighters" or something like that.
Now I got to name the first level soldier "Tiefling Jerk" and the skirmisher "Tiefling Nimrod"
