For Perfidious Albion: A Scientific Romance, I recommend either GURPS Lite or FUDGE. Even more, I recommend any good steampunk fiction, such as The Difference Engine, Girl Genius, The Two Georges, and so forth.
Some good references for steampunk, and for the Victorian period in general, are:
* What Jane Austen Ate and Charles Dickens Knew: From Fox Hunting to Whist -- The Facts of Daily Life in Nineteenth-Century England by Daniel Pool (available for cheap on Amazon.com);
* An Incomplete Education: 3,684 Things You Should Have Learned but Probably Didn't, specifically the section on English Literature, which discusses obscure details of nineteenth-century British life (likewise available for cheap on Amazon);
* GURPS Steampunk by my old friend Bill Stoddard (available for cheap as a PDF at Warehouse23.com), hands-down the single best reference source for the period, whether realistic historical or steampunk.;
* Forgotten Futures: The Scientific Romance Role Playing Game by the brilliant Phil Masters (available for free as shareware, he asks that you make a donation to charity, God bless him!)
* Comme Il Faut, a supplement for Castle Falkenstein on daily life and manners in the 19th Century.
(For what it's worth, I did graduate work in English literature and specialized in both sf/fantasy and Victorian/industrial revolution fiction.)
I prefer "system" games, because the system helps answer questions like "How far can I jump?" and "How long will it take to fix the engine?" I strongly believe in a good story rather than rolling dice, and I also believe in realism and balance.
Above all, I want to make sure that people who are interested in the genre and/or the setting, and are not familiar with the system, to join and play and learn the system as we go along.
For more information about the game, or if you wish to join, please contact the Management of the game via electronic mail for any questions about the setting, or for the Approval of Characters.
