I fancy myself as a Casual player, although several friends from the old guild back then pointed out to me that I should be able to play in Advanced as well.
I admit, I simply don't have the courage to try on Advanced. ^^;; I can write down about 1-2 paragraphs, and maybe more if I'm trying to describe something, and that kind of writing should be placed in Casual (or maybe High-Casual) instead of Advanced, IMO.
I take a look at Advanced and sometimes it feels like I'm reading a whole story on its own within a post. I know that not ALL of Advanced is like that, but it sure seem that way for me.
Another thing is, I'm the kind of player who tried to pay attention to details to avoid inconsistencies. What was my friend(s)' character doing? Did they do anything related to my char or in a completely different scene that has nothing to do with my char at the moment? Did they interact with my char? Or do something that could affect my char? Things like that.
I tried to pay attention to those things so I can write my char's responses or reactions accordingly, something like if like 2-3 other characters were trying to talk to my char, I could have my char responded either to all of them one by one, or like focused on one and ignored the others (I'll write down that my char was pointedly ignored the others or didn't hear the others' question)
In Advanced, there are a LOT of details being thrown within every single post, and I can already feel my mind approaching its boiling point just by trying to taking in all the details. @__@ I have no idea how to keep up, so I'm sticking in Casual, well, 1x1 Casual for the moment.
