Its worth reminding everyone once again that "DM judgment" is a valid system for resolving things in an RPG. I think this forum's D&D focus sometimes obscures that fact. The DM is a tool the game can use to resolve things. Using this tool instead of a written rule does not make a game "incomplete."For me this again makes me wonder why I am paying to have an incomplete game, IMO in more ways than one,.
I don't know how much that really affects your conversation, since I kind of feel like your discussion of completeness is a red herring in the first place- it seems like what you're really discussing is the degree of abstraction a game should use, and how easily you can or cannot add that specification back in to 4e.
All I can say on that is that its easier to add in details when you've been told the mechanical baseline by the designers than it is to add in details when you have not been told the mechanical baseline by the designers. Of course, after eight years of playing 3e, I already know the mechanical baselines- and you probably do too. So that doesn't speak to us personally.
That's an entirely different question. If you don't like the newer system better, then you probably shouldn't buy it. Like I mentioned above- there are a lot of small innovations in 4e (openly providing the DM with a "behind the stats" take on the game and advice on how to use it) that are of little to no use to someone who has, through experience, trial, and error, already learned the "behind the stats" take on 3e and how to use it at the table.when I have a pretty complete one and know it well enough to tweak it to my desires. YMMV of course.
