The one true test for me in 4th Edition is whether or not it actually simplifies the rules or not. If it does not and instead just forces everyone to learn a whole new set of rules (that may be more thorough and balanced) then the DM is going to have to work harder again to get to any aspect of the roleplaying side of things....
A good game to me (when I DM) is when every player is engrossed in the adventure and their characters - any action typically runs smoothly and is exciting with very little disruption due to the simple flow of the rules within the battle not hindering the atmosphere or suspense that has been built up.
Have to admit whenever their has been a new version AD&D from 2nd edition, 3rd edition from AD&D etc there is always a down period where players and DM struggle to get flow within the game due to the constant referencing of the rules and interpretations of them.
So I guess the question really is whether or not people are prepared to re-learn everything all over again.
I probably will, just because I am a D&D/Mythology/Fantasy fanatic but the question will just have to remain with the non-fanatics....are they prepared to put their money down to buy an entire rollplaying game set of rules all over again...
