Saturday's session was frustrating and instead of having to break up around 10pm for those players that needed to get home to their families, I ended up ending the session at 9:30.
I don't want to point fingers at anyone individually so I'm not going to go into detail (in case they read this here blog). And I'm not entirely sure that its any of the players' fault.
As I dwelt upon it, I've realised that when I last had a regular group that I DM'd for, it was back in 1992 and nearly everyone was military. And why is that important? Because everyone was used to being presented a scenario with basic assumptions and then were able to work together in accomplishing the tasks necessary to realize their goals.
We still had odd-ball characters, inter-party strife, randomness, etc.; in other words, fun. But we didn't seem to get distracted by every little thing or have PC groups within the PC group.
Does any of this make sense?
