We try to make everything a game ("Let's see who can remain quietest the longest"), but even the slowest child sooner or later tires of a particular game. This is why I say make it a routine, not a game, because then it's a given, not a negotiation. So, sure, you can make it a game to brush teeth each night, but then you have problems the night that the kid want's to play a different game with the toothbrush. Making it a routine avoids that problem altogether.
