Returning to Feng Shui

I am returning to the game after not having played since 2009 or so. It’s my wife’s favorite game system and I just recently ran the test drive rules for FS 2… I think I want to run a long-ish campaign and use a lot of the books I’ve bought for the system: Which happens to be just about every book I could find on Drive-Thru as well as the in-print books I already owned.

There doesn’t seem to be an overly large mechanical difference in rules between FS and FS2- if I’m wrong could anyone tell me what I’m missing?

My understanding is that the principal differences lie in the archetypes, which are more balanced and more streamlined. In general, the whole system has been streamlined to remove a bunch of things that seemed terribly necessary back in the 90s but actually don’t accomplish much in a FS game.
