Every now and then my boy and I set up army men, and play "daddy games", or our version of wargames.
We deploy our armies, roll dice and have a pretty big blast. He enjoys it quite a bit, and hopefully it will cement his love of wargaming for years to come.(my wife hopes otherwise)
Here are some pictures from our most recent encounter, where, for the record, I was beat solidly, twice in a row. :)
