I was at an Anne McCaffery book signing many years ago and some guy asked her what her advice on starting writing was she replied something along the lines off.
Quote:
Write about 100 page novel, put it in a bag and forget you ever wrote it.
Then write another 100 page novel, burn it.
Write another and let your best and most knowledgable friend read it, don't be upset when he tells you how bad it is.
Repeat that until he no longer hates it, then burn it.
write a 50 page novelle of the best stuff and compair it to the first one, if there isn't SIGNIFICANT improvement don't bother, if there is then ask a publisher to have a look at the 50 page Novelle.
SHe claimed that a biginning author should write and burn about 1,000,000 words before approaching a s publisher, adapt this advice to games and follow it.
