You don't need fluff to play an RPG. You only need imagination. When WFRP1st edition was out, and all we had was the Enemy Within campaign, we had just enough fluff to play. Today we have a 1000 times that and don't need it.
You want to create a town? Pick up a german town name, say Scharzburg. You want an NPC, do you really need Stat Block for it? Just give it a few dices for what the NPC will be used for.
Players and GMs are making RPGs too complex. An RPG is about imagination, not books after books of fluff or rules. I doubt FFG is going to release many books of fluff for EotE. Why would they, it's a big Star Wars universe with so much available already… it reminds me of another universe, ah yes the Old World.
All what we need are scenarios. FFG has produced many scenarios in all those supplements, and if a playing group goes through all of those, that group should have enough experience to create their own or to play without pre-written scenarios.
It is tiring to be hearing about what WFRP3 needs, the death of WFRP3, how FFG screwed up WFRP3 because there are bits and so on. This board has become a downer. The game is playble, fun to play, easy to pick up for new GMs and new players. It's a game! Just a game! and a good one. It has flaws, what game doesnt? FFG did their best, they did their parts, let now WFRP3 rest and be the mature product it is, with small but continous support as it should be.
If a 4e edition comes out one day, wonderful, one more game to the serie, if it doesn't we have enough of the 1st, 2nd and 3rd to enjoy the Old World. Let's stop bitching and continue playing.
