Are you talking about PC backstory or adventure background information?P.S. on backstory. If backstory was ever any good, it would be main story. The less explained it is, the broader the strokes, the better it is.
I love prequels. (Yes, even the Star Wars ones.)Obviously this is just my opinion, but think of the last prequel you saw and ask yourself how it held up to whatever the main story was. There are very, very few prequels worth their own full treatment.
