I don't think anyone is going to have their mind changed by these articles about third versus fourth, or have any of their reasoning challenged. The new system has been out long enough now that if someone's quarrels are based in concrete, systemic issues, they've had time to explore that and decide already. And if there's any pure dogmatic dislike lingering, then it's probably not going to fade anytime soon.
But one thing I think this series might help with is the perception of 4E as an industry product. A lot of gamers see 4E and its changes as a big 'fuck you' from Wizards to the corpse of TSR, and I think that's a terrible thing. This game wasn't designed to replace 3.5, and can't anyway. 4E was designed by people that have played and enjoyed tabletop gaming since the early years of the hobby, since there was no such thing as a tabletop RPG industry.
If there are any people out there who have held prejudice against 4E because of perceived meddling by businessmen or outsiders, regardless of actual, physical qualms with the system which may be perfectly valid, those ideas can and must be challenged when you face the fact that these systemic and stylistic changes where made by people that have been gaming for years and years, possibly longer than you, even. When you have to examine the thinking behind the new system not as the product of an industrial machine but as the brainchild of red- and blue-box gamers that you couldn't tell apart from your own favorite group of nerds, then you have to begin to respect those ideas, even if you still don't agree with them.
Think about your gaming group. Do you all agree about every aspect of your system of choice? Do you even agree about a system of choice? Not likely. And when they say something about the rules or materials that you think is insane, hopefully you put up with them because you have had some amazing adventures together, and when you're in such close quarters you're far more likely to see 'personal preference' instead of 'sabotage.' What a concept, huh?
4E was made by the same bunch of nerds that pile into your rec room every few weeks to sabotage a lovingly-crafted campaign for the sake of free snack food. They all have dozens of hilarious and inspiring stories about their past and present gaming groups. They all have passion and love for their hobby, and I bet they consider themselves some of the luckiest people in the world to be able to have a hand in its future. I don't know how they feel about disagreements you might have with 4E's mechanics or umbrage at its stylistic changes, but I can't imagine how shallow and hurtful it must seem to them when they're regarded as outsiders, middlemen, suits, or 'people who just don't get it.'
Everyone has played with and enjoyed the company of the one old, tireless codger at the table who, regardless of his grudging tolerance of and affection for the new generation, always held such fervor for bellyaching about how much he misses THAC0, how he's fought far more harebrained creatures than flumphs, how it used to be that the DM really was just out to kill you, and how you 3.x kiddies just can't understand what it was like to play with the late, great systems of yesteryear. Maybe you'll have the privilege of being that guy someday whether you want to be or not!
3.5 still exists. So does AD&D second. So does first edition, which I could pick up from the gaming shop in my town any time I feel like it. The existence of 4E doesn't in any way prohibit you from enjoying your hobby, but it may allow someone else to do so, and I'm sure that's what the designers were thinking about. So please, can't we just develop some kind of alliance, if not agreement, and get back to raving about those clueless maniacs that make and play White Wolf? I mean, seriously, what were those brain-dead World of Darkness dolts thinking when they-
Sorry. You know what I mean.
