The Namco Tales fan group that I'm in has recently gotten in the habit of posting as characters on their facebook page, using "skit faces"--in Tales games, in certain parts of the world map, if you press select in certain places on the world map, there are "skits" in which the characters have conversations with each other, like this infamous "bazongas" skit from Tales of Xillia: https://www.youtube.com/watch?v=heRVYqvSRvI
So anyway, you can find the sets of expressions used for those skits that people have ripped from the games, and like I said, my group has been using those to post in character...it's basically a form of RP, but it's kind of interesting because it's also a continuation of what goes on at our conventions & meet ups between the cosplayers (people who dress up like the characters--most of them RP the same character online). You might be able to see what I'm talking about if you go to the page: https://www.facebook.com/groups/435747049779517/
Okay, the thing I was just talking about has just spun off into its own Facebook page: https://www.facebook.com/pages/Tales-of-Roleplay/749423671743576
Oh dear. I've really gotten into this now, and somehow, I am now offically a fictional character on Facebook:
At least until I get some sort of cease and desist from Namco...but I'm probably pretty safe since the character is over 15 years old and from a game that hasn't been localized in the U.S.
