We dedicated roleplayers have an edge when it comes to knowing what our characters are doing when we’re not out slaying insane stuff because the storyline/quest completion requires it, yes, but we all think about it. Oh, sure, your Charr Engineer doesn’t have an elaborate backstory written, but you still think about his kicking back in a bar and enjoying a few drinks. Your Cyborg Sith Inquisitor enjoys a card game. Your Human Warlock has a pet cat.
Some MMOs have tried to figure out what your characters are doing when you’re not online, with varying degrees of success, but how do you see it? What do you imagine your MMO characters get up to in their downtime? Even if you’ve never considered it before now, why not consider it now? Maybe your favorite character is really into karaoke. That’s a normal thing, right?
