I dabble in other fandoms these days, too. But SGA always calls me home after a few days LOL. SGA does have a lot of open threads to tug on and explore. Not to mention the possibilities of alien worlds, space travel, etc. There's still so much to explore, plot wise. But with characterization and such, we've seemed to have all settled. John is always gay and pining. Rodney is straight and oblivious. John's mom is always dead. Stuff like that.
