What are some differences between all three types of RP? To my understanding, Casual RP is the shortest writing, and Advanced RP is Novella-level writing. Are there any other differences like for Casual RP, is the story shorter than Advanced RP? For example, are Intermediate RPs usually a full story, and Advanced RP usually a series?
The only difference is the requirements of post length. The story and everything is all dependent on who you end up rping with and where the course of RPing takes you.
