Earlier today, I bought the d20SW supplement 'Coruscant and the Core Worlds'. I don't have the revised d20SW book (although I do have the original), and don't plan to run a d20 Star Wars game any time soon, if ever. But I am running a Star Wars game with the Feng Shui rules set, and CatCW has some great info about a plethora of cool planets, not to mention some awesome adventure hooks and a bunch of useful NPCs.
I know that a bunch of people use the GURPS culture books (GURPS Russia in particular, IME). I've found that RPG resource books are best when the info in them is mostly system-nuetral, but there's enough crunchy stuff to keep you happy if you happen to be using the expected game engine. Does anyone else purchase RPG setting or info books, and use them with a game that they weren't designed for?
