Q: What kind of writing samples do you want for game work?

Gunther Winters is looking for a writing position in the gaming industry. He says:

...all those ads [that interest me] require the submission of "samples" of one's own work, and I suspect that those that don't clearly require it just take it for understood. ...what is adequate for "submitting"? How many "pieces"? How long? Of what  kind? Most ads mention no details whatsoever...

Any other advice for an aspirant "writer" who is trying to approach the gaming industry?

I can't tell you specifi...
