Our group has been looking to add some new blood and meet some new gamers for our fall session, and we've already had 4 serious responses to our efforts. Our town was generally thought to be largely bereft of a gaming scene, but like most little to mid-size midwestern towns, I think it's there, it's just waiting for the right sort of outreach. To this end, we've tried several different approaches:
-Basic word of mouth. Told friends to tell their friends...
-Fliers. Seems old-fashioned, but I think they help. We've put them or are putting them in RPG books at bookstores, in cafes, the library...
-Adverts for new players at places like RPGnet and ENWorld (which, however you may feel about those two sites, they still get a lot of traffic)
-Hitting up the local Indy Gamer and D&D Meetup groups at meetup.com.
Really, I think it's the mix that's helped. I think we've had one response from each thing we've done, and we just started our push this past weekend! Not too shabby!
I think it helps that the setup for our Castles & Crusades campaign is going to be a sandbox game that's a bit easier on attendance. I believe we're going to try for initial meetings/meet n' greet over the next two weeks, and start our campaign by next month's end. Should be a good time for all.
I think one of the big things I had to do personally was adjust my expectations. Many of us have kids now; we aren't going to be able to do a marathon session every Saturday. It just isn't going to happen. But we can do a biweekly game (occasionally more frequently), late on Fridays, where it doesn't interfere with most schedules. And I think in the end, that's more rewarding than trying and failing to do something more frequently intense. If you're struggling through the same sort of decision, you're not alone. The quality of your gaming doesn't have to suffer just because you're older, with more responsibilities; we just need to adapt and overcome (that just sounds wrong, coming from an Air Force alum).
Like in many things, managing expectations and ensuring everyone is on the same page before starting out are vitally important.
