My main concern is scheduling - or rather, players' lack of commitment to attending regularly. We have one or two players who appear to ditch, often the day of or before our bi-weekly scheduled session. I think they're often either tired from lack of sleep discipline or they want to stay home and play videogames.
I can't really say much. Our group consists of me, my son and daughter, and my son's two friends. The attendance issue is with the two friends. Despite my frustrations with their lack of commitment, our game is very important to me because it helps me to stay connected with my son, with whom that can be a challenge.
They're all in their late 20s and I'm the old guy in my 50s. I sometimes feel like their generation has grown up with a diminished sense of commitment in general. (I know I sound old when I say this!)
When one of the friends can't make a session, we either play without him or, if we're expecting a particularly important or climactic session, we reschedule.
As I said to my daughter a while back when I was feiping about it, it's frustrating to know that people have significantly lower levels of commitment to an activity you share with them.
BTW I'm eager for any solutions here.
