Man, I'm surprised Star Wars: The Old Republic is still trucking along. You have to give it to BioWare (and to some extent, EA) for staying with it after its mixed reception at launch, so-so expansion packs, and its transition into free-to-play. I was there day one, and promptly quit after reaching level 50 as there wasn't really a whole lot to do after I had experienced a few of the stories.
But with the newest Knights of the Fallen Empire expansion that launched last week, I'm back in, dabbling a bit with old and new characters alike. It's a marked improvement.
