In my honest opinion, I believe that roleplaying such as this fits in its own category. You don't find interaction this dynamic in advanced, but the plot direction and advancement goes in such a way that it also wouldn't fit in casual. Sure, there are stupidly long posts just like in advanced, but it isn't because the IC thread is 'EVERYONE WRITE YOUR OWN NOVEL LOL'. It's due to the fact that we are putting interactions together in one big lump sum. It ends up being more readable, cohesive, and kind of... serialized, I guess? Episodic? No definitely serialized.

Not like I'm looking down my nose at everyone in Advanced it's just... I've [i]been[/i] in Advanced, man. RPs don't last very long, they take forever, the pace is horrible, it always feels [i]just[/i] a bit stuffy and pretentious, and even if the RPs do last, they usually are never RPs I'd give a shit about joining anyway.
