Okay, I agree that eating meals is silly, but it would break immersion if there wasn't any food anywhere, so it's necessary, but I don't sit down and eat in taverns or anything, that's going too far. It's not so much in-game story I make up, as much as back story, but that's nothing more than the simple stuff I posted above.
No, one cannot live in a game, but games are a welcome break from the incredibly boring thing known as life. It's not always that boring, but when it gets that way, there's always something that never gets dull. So what if someone takes a little extra time and enjoys the game world, though? I used to be, and still am to some degree, a story teller of sorts; and if I've learned anything, it's that one cannot tell a story without practice (and roleplaying in a game can be great for that).
No, before anyone freaks out and asks, I'm not a bard, sorry, last I heard, bards died out with knights in shining armor. The same skills do apply in modern times though...you probably know more bards than you think...
