Not sure if anyone already posted this but ths is an interesting read from Graeme Davis on his thoughts around the new (and old) Enemy Within, and third edition. http://graemedavis.wordpress.com/2013/01/02/the-enemy-within-arrives/#comments
Having GMed this game twice today at a convention for comple newbies I have to say I agree absolutley with his statement that the bits help the game run smoothly. Granted the players were not new to RPGS (some Pathfinder guys, a few through RPG video gams etc) but there was little lag between a 5-10 minute "heres how it works" and good times and great characterizations. And there is alot of complexity to the game rules as written.
