My two cents on the advanced/casual thing: I prefer advanced RP generally, as I rarely have trouble writing a decent amount and I much prefer better description and character development and yadda yadda yadda (the principle reason my CS is sparse in backstory/personality is that I prefer to discover characters in RP - I'll figure out how he acts, but those are my guidelines).

The main reason I tend to stay on the casual side is because posts tend to come much faster here and RPs are less prone to crib death - oftentimes I'll really like the idea of an Advanced RP, but it'll take everyone a week to fill out the massive character sheets and they'll never get off the ground.

So... high-casual stuff like this is ideal for me, I'd say.
