Nice AAR. I got into TtS in sort of the same way. My Punic armies suddenly had enough miniatures for this fun new game, and they had never actually seen a wargames table before.
Just as you did I also play it a lot with my 10-year-old son and his friend. We have tried Punic Wars and various medieval periods with great success. I have asked then if they want to try out different rule systems, but they like TtS, because the rules are easy to pick up and allows them to concentrate on the tactics instead. Something that is far from easy to pick up, and they are learning it the hard way.
Cheers
Erik
