To me, it really doesn't matter how good a story is...if it's a wall of text, I skip it.
However, I do think people should make an attempt on the forums to develop their characters.
It doesn't have to be "good" & it doesn't even have to be read... but on the forums a person has the opportunity to do things with their character that go beyond the scope of the game mechanics, & thereby giving the characters a little life, that just sitting in the cockpit & talking on the radio to other pilots in between fights will just never match.
Even if it's nothing but a personal log that only outlines what the character likes to eat for breakfast, it gives the person creating the character the chance to get into that character's head, & either conciously or sub-conciously helps the creator RP a little better on the server.
Alot of people have low self-esteem about writing...screw all that.
If you can speak words, you can type 'em out.
Just don't worry about what other people may think of your skill level.
