I keep going back to Star Trek Online for some star ship pew pew. I usually get a month or two in going back over the story arcs and participating in events until the constant event schedule makes me realize I'm trapped in the grind and not playing any other games. So I drop it to break free and play the rest of my game library. The community isn't something I really interact with as pretty much all of the game content is playable solo or antisocial (the team content is easy enough you can just random queue and don't really have to talk or strategize with them). It is overwhelmingly PvE (though PvP is technically in the game) and it has some fun lore if you are a Star Trek fan.
