Forgotten Futures has everything you would expect from a professional RPG: an introduction to roleplaying, a clear index and glossary, detailed equipment tables, solid GM chapters with plenty of examples of play throughout and don't forget the many supplements for the core book. Overall a very solid effort underlined by the fact it is absolutely free. If only every idie RPG was up to this standard.
Rules-wise FF is a vanilla rules-lite 2d6 point buy system with damage saves. No prizes for originality and “game balance” here, but the upside is that you won't have to spend weeks learning rules and hours creating characters. In fact, any GM worth their salt should be able to run a session after a quick skim.
The game system takes a back seat to the real meat of this game: GM chapters on how to run every conceivable variation of Steampunk genre and believe me, there are a lot. Want to outwit Victorian era version of Daleks from Dr Who? There is one in the gadget chapter, complete with telescopic eye and Maxim gun. Saving Martian Princess is more your thing? Hop in the space yacht!
There is plenty of material to run every story by Jules Verne and League of Extraordinary Gentlemen. Anyone who wants to know more about steampunk genre will find a handy (and lengthy) list of sources in the appendix – invaluable for getting a feel for the genre and mining for adventure ideas.
Forgotten Futures is THE steampunk RPG. A very solid B from me.
