Thorvald,
I should clarify,
I want the rules cyclopedia on ESD. The pile of books in front of my packed bookshelves is already too large.
I liked the clean rules of basic, weapons and combat were simple and straightforward, ability bonuses were standard across abilities, but unfortunately thieves still had crappy skills and saving throws were in wierd categories with wierd progressions.
I liked the weapon mastery rules for different reasons. I played in an campaign with weapon mastery rules, modified, expanded and tacked on to AD&D and they were great. My wizard merchant prince was a grand master of merchanting! Also I saw dragons that were masters of claw, and experts at wing buffets, as well as one that was a grand master of Feng Shui.
Regdar,
It is a lot easier to run a quick combat without miniatures in basic than in 3e. The options and complexity of combat (attacks of opportunity in particular) are very different in play styles.
