So, my four year-old daughter has discovered that daddy's tanks can waggle and make funny noises when they shoot each other. She seems to be completely on board now for tank battles.
...the problem with this, however, is that her idea of a tank battle amounts to one tank shoots another until it shuts down, and then the other tank shoots the first until it shuts down. Completely absent from this is any actual driving, or maneuvering.
...oh yes...and turning on tanks summons an enthusiastic little girl.
The good news is that it's really easy on the batteries when the tanks aren't actually driving anywhere. The bad news is that, um, the tanks aren't actually driving anywhere.
