I have difficulty gaming with people who don't take it "seriously." And I agree. Why wouldn't you want an on-going campaign with a full-fledged storyline? I swear it's the video game influence in youngsters.
Sheesh. Gee-whiz! And all that other stuff.
I currently have a game that I run with my kids. I have all but one child who is interested in gaming and one of my sons' girlfriend plays as well. Seeing how they are in Utah, Idaho, and Connecticut I use Roll20.net. What I've found is that I'm out of practice as a tabletop GM. Giving descriptions is more difficult than it used to be, jumping in and out of NPC skins is challenging, and even the storyline has become troublesome.
Maybe I'm just getting old.
