I generally stick to Advanced because of my time restrictions and RPs in that area are flexible with how long you have to post. That said, in my experience with RPG, High-Casual has been more-or-less a topic of conversation already engaged when I came around five years ago. What I have concluded is the following: 1) High-Casual is meant to draw more serious participators OR are meant to draw others too put off by Advanced, and 2) If the Advanced stigma melted away and High-Casual came on over, we'd have a wonderful, fresh, new population.

So basically, I have much anger toward High Casual. Advanced is not at all as intimidating as it might seem. How the RP goes is based on the people and you can easily shape that to fit you. I want people to aspire and reach for what they'd like -- no fear, no hesitation. I'm not sure where the stigmas arise, but they need to die. Free, Casual, or Advanced, we love to write and we should do it in whatever category we desire.
