I heartily dislike being pointed at with any toy that looks like or pretends to be a gun. I never forbade my son to play with toy guns, but I didn't give them to him myself, and he was not allowed to point them at me. But that was just expressing my opinions about guns and expecting him to respect it.
Re games - some children do get more easily hooked than others. Like me he has the ability to block the entire world out and concentrate for a long time on one thing, whether it's reading, watching tv or playing a game, and has trouble breaking out of it. So we have to limit his computer use every now and then - but that also applies to reading. Sometimes we have to argue for ages to get him to join us for something outdoors, even though he's been out camping, fishing, skiing, biking, kayaking, rock climbing, you name it, since he was tiny. And he loves it! It's just changing whatever he's doing at the moment he hates...
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
