Actually many of my roleplays ended up turning into our comics. We have a joint company, IEK, in which several of us create long winded role plays with original characters, then draw them out. It's actually a very long process of writing, editing, and planning, but essentially the same thing. trust me, makes writing dialogue much easier, especially since different people SPEAK differently, it's great to use other people.
All of our roleplays are very long, and written like a book. Large and long sentences, fully written out the actions and dialogue of the characters, large paragraphs. They can go on for months. Thankfully we just finished one.
