I used to play PnP all the time. Had a good group of players with some of them good DMs as well. That was cool b/c I didn't have to always be the DM. As Neb stated, that does get old after awhile.
Unfortunately, I just don't have time anymore. Life has taken over. As I get older, I collect more and more "baggage" and find that I have very little time to myself anymore...barely any time to play BG2 as it is.
BTW..."baggage" = wife, kid, dogs, house, yard, cars, bills, school, work, family, etc.
Growing up is a real drag!

Now where did I leave that doughnut?!
