wow.
Now, I have a measure of regret for always being in a bit of a hurry to get things done while playing. Looks like I missed a lot of stuff.
Sonic Girl Seven was my favorite of those I read.
However, they all remind me of one character that was invited to one of the Dreck farms I was running on Triumph back in '05 or '06. I didn't know the player, and don't think I ever saw them again. I truly wish I had a screen shot, but I think you should be greatful that I do not.
Naked Mole Rat
The player behind the character, well, I didn't know him, so I've no idea if he was into role-playing, or just casually over-used the word chum, referring to anyone he was addressing.
Honorable mention goes to "Panda Poacher" -- a player whose global name escapes me, on Liberty. (I think it was @godman)
@hazygreys had sponsored a Panda costume contest - the character that most resembled a panda bear would win some humongous amount of influence, even by inflated standards. 1 billion or some such.
As the judging was taking place - Panda Poacher just appeared out of nowhere - could have been a teleport, or could have just logged in - it was one heck of an entrance. <sigh> I think you probably had to be there.
