This is some people's preference. But plenty of games don't have such a distinction: all versions of D&D, Tunnels & Trolls, Marvel Heroic Roleplaying, HeroWars/Quest, plus innumerable others. These are all good RPGs that are widely played and enjoyed.
Indeed. But (inasmuch as I've seen), those rpgs don't have the identity crisis on this issue that D&D does. I (and not just I) am unsure with regards to any version of D&D to what extent the rules are strictly the physics of the game world, and to what extent they are metagame constructs. With, say, MHRP, it is clear to me that the rules are not strictly describing the game world, they're creating plot. Metagame rules aren't inherently a bad thing.
What I think causes problems is when it's not clear what a rule means. How much are hit points about physical characteristics, and how much are they skill, and how much are they metagame? I can't tell. Can you?
To me, hit points are an example of a rule that lacks transparency, because no one seems to be able to agree on what they mean.
The innovation you're talking about already exists.
Most innovations do already exist before they're widely adopted.
Certainly most anything in 4e that one might describe as "innovative" (and use as an excuse to criticize others for resisting change or holding back innovative) already existed somewhere. My point in this regard is how do you define sacred cows? It seems remarkable to accept changes aplenty while in the same breath (or post, as it were) quoting a deceased writer who hasn't written any of the last three editions (at least) now of D&D as being the definitive authority on the subject.
That's true as far as it goes. But I think your preference for process-simulation, world-exploration RPGing makes it hard for you to understand what others are doing with RPGs that you're not interested in. You seem to infer from the fact that they don't support your preferred approach to the fact that they're no good as RPGs.
I can't say that I'm real big on process-sim or world exploration; that seems an odd assertion. (Rules as physics of the game world isn't the same as process sim). That being said, I don't need to understand all possible perspectives in order to draw conclusions about a game that is labeled as being a new edition of one that I already play. If a game is marketed to me (and foisted on me by a few posters as [MENTION=6698787]timASW[/MENTION] describes), it has to fit my needs and work with my style in order for me to accept it and it has to read well in order for me to buy it. If I'm not convinced that it does that, it is not incumbent on me to adopt or even understand the mentality of its designers. I don't know whether or not 4e is good for
something (nor is that relevant), I just know it doesn't meet the criteria that I personally have for it.
By the same token, for example, I don't need to watch all of JJ Abrams' movies in order to critique his Star Trek reboot, nor do I need to study and understand his style or philosophy of film-making. I already know what Star Trek is to me and I can judge a Star Trek movie on that basis. And someone else with a different perspective is welcome to (and will probably) render a very different judgment for very different reasons.
I don't know how you can know this is true as a general rule. Also, from the fact that some people's enjoyment might be semi-independent of the game system, it doesn't follow that the game system isn't relevant to producing that enjoyment.
I know because while D&D-style tabletop rpgs are a relatively recent innovation, roleplaying is one of the most fundamental forms of play. The ability to do it is a developmental marker. And people enjoy doing various forms of cooperative storytelling without rules, and have been doing so for far longer than we've been around. I feel comfortable with my reasoned conclusion that an individual roleplaying experience is not primarily defined by game rules (regardless of what the game is), because those rules themselves are an optional part of that experience.
I don't feel comfortable saying "Edition X fixed this issue for my game (or my game and my friends' games), therefore everyone has the same issue and Edition X will fix it for them", let alone "Edition X is balanced and this is objectively true, while all other games are unbalanced".
