I've written a game called Fourpenny Touch which is about the lives of the women who will be killed by Jack the Ripper in 1880's Victorian London.
I'm having a setting section so that players who aren't particularly familiar with the background have some understanding of the situation of these women. In some ways this is similar to Steal Away Jordan which has details about slavery in the South, the historical setting and the daily life of such people.
What I do want to do is provide something that is seen as useful by the players. Not a massive amount of reference but something that gives the tone or feel of the situation.
So, my question is, if you're going to play this game, how much background information do you require?
And by this, I mean you personally, not some other hypothetical gamer.
If you know tons about prostitution in the Victorian East End, then please do say so. If you've seen From Hell and think that tells you enough, that's fine too. If you see this as a passion play for everywoman with no need for specific historical context, that's also good. If you want to know what the fourpenny touch is, the cost of bootlaces, life expectancy, the racial mix and the legal niceties of prostitution then that's of interest to me also.
