There's definitely no emphasis on length over quality. Quality writing is what we love to see here. Some of us write longer than others, for sure, but there are also different styles within that. I might as well be the first to tell the story, but one guy went because he dropped a 14k word rp and didnt understand why he lost. Length doesnt get you a win alone.

The best advice I can give you is see how everyone rps, and what's successful. Don't get caught up in a length mentality.

As far as making your own work longer, just let your character evolve, and that extra 'girth' so to speak will come in time.
