never allow tv while playing, thought about banning iphones as well, but the novelty has worn off now ... that doesn't mean that people don't talk about computer games, but that mostly stops when we begin playing. I do however love playing with a physical battlemap, we don't use miniatures but just 1x1 inch counters, that gives us the advantage of being able to print all monsters with the right look, whereas when we used miniatures it was,.. ok.. these orcs are now drows .. next encounter, now these orcs are trolls.. so they take up more squares.. with printed counters we get the size right and the players can see what they are up against
I'd love a digital map, but it should be lighted from below (like that Micro$oft table), so we still could use our counters. And dice rolling is a must too - physical ones!
