Re: Looking for a game: D&D 4E (pref), maybe 3.5, maybe Rift
I've tried to join groups before, but, like the one 3.5 session, people will show up once and then ditch. I'm looking for a group that will meet up at least semi-regularly and willing to deal with my knowing very little (as the live group hasn't been very understanding), though I do try my best to pick things up quickly.
Building groups takes time. I can't begin to tell you how much effort it takes (and that's coming from the perspective of a DM). So if it seems painful to you that all of the groups you've been involved in have barely gotten off the ground, imagine how much more effort it takes for the person in the top spot.
And I say that as someone who runs a very successful game on OpenRPG that's been around since 2003.
There are groups out there (unfortunately my Saturday group is not recruiting at the moment (and even if we were, it's not your cup of tea because we play with an older edition of D&D)); it's just a matter of perseverance on your part, and a little bit of luck at finding the right group.
Best of luck to you.
