Thoughts? Let me have it.
I believe that there are few actual beneifts to Edition Wars. One benefit is that they can elicit feedback (of a sort) from people who otherwise would not say much. Another benefit is that the debate can force some people to examine their own views critically and make a complaint more specific; A statement for 'This new edition sucks' does not help. A statement of 'the new rules feel too mechanical and break my suspension of disbelief' is a bit better. A statement of 'Warforged, Tieflings, and Dragonborn do not belong in my game' is actually helpful feedback.
The problem with Edition Wars as I see it is that it is a rather bad term. Entertainment is a highly subjective topic, and people tend to promote personal views as being 'the right view'. People are also capable of liking the same form of entertainment for entirely different reasons while also disliking what the other person likes about it.
I have played since 2nd Edition, and I happen to be a fan of 4th Edition. I like that a great deal of effort was put into making the game mechanically balanced. I enjoy playing D&D as a whole because I enjoy the responses to the various decisions and problems that the PC's face, and the free form options open to the players. I enjoy the tactical combat, and allowing for the posibility of the players failing. I like using minis for combat as they automatically prevent confusion about line of sight or who is adjacent to whom, or how many orcs are caught in a fireball. I disliked the idea of magic users being in practice a great deal more powerful and effective then non magic users. I hated super fragile low level characters. I am indifferent to historical accuracy, and simulationism. I am also indifferent to the character races.
However, there are people who enjoy D&D, who have played the exact same editions I have, that cannot stand the elements I like. Some people run game worlds that are very much like Toilken and have no place for Dragonborn. Some people are convinced that melee types must be limited to what a person could accomplish in the real world, and find the concept of daily exploits for fighters to be utter nonsense. They are bothered by the idea of magic users not having unrestrained magic. There are those who love the game but hate the idea of hit points for tracking injuries. There are those who love the storytelling above all else and get annoyed when the DM creates encounters that are too time consuming. There are those who find mini's cumbersome and annoying, and hate the dependence on them. There are those who hate the idea of 'super powered' PC's being so much more powerful then regular NPC's at the start of their adventuring career. Some just cannot accept the notion of a level 1 Kobold that wont die in one hit.
On top of that there are people who will dislike a particular edition for reasons entirely unrelated to the actual gameplay. Some people hate a new edition because the previous edition was not that old, and see the new edition as a cash grab. Some dislike powercreep and the constant stream of splat books. Some dislike the use of a software tie in because they do not want to bother with a computer at the game table. Some people will dislike a new edition simply because they are convinced that a previous edition already got everything right the first time. Some people just hate the 'flavor text / fluff' provided for the new edition.
Regardless of what causes someone to like or dislike any particular game, the basic fact is that every one of the elements I mentioned above are perfectly legitimate reasons for someone to like or dislike a game. There is no right or wrong, only that which affects your ability to enjoy a game. But because everyone who plays D&D tends to take the game more seriously then they ought to, the edition wars tend to outlast any amount of reasonable benefit they could have.
I think that arguing the merits of 3rd Edition vs 4th Edition is about as productive and reasonable as arguing the merits of a Corvette vs a Porshe. Both are fine cars, and in practice anyone who likes nice cars would probably be happy driving either. There are people who would prefer the Porshe, and those who would prefer the Corvette. And among those, there are some who would consider people who insist that one of the cars is crap and the other is awesome to have their head on backwards.
What I wonder is why the hell one guy would give a damn what the other guy thinks of his favorite car? Peo[le in general are not good at accepting that someone will disagree with them about a topic that they feel passionate about.
