I like to think everyone is finally realizing that we are all gamers, and THAT is the commonality we should worry about, not what is thought to be the "best" edition around. We all, presumably, have fun playing what we play, so why try to insist whatever it is we play is superior to everyone elses.
Kind of like Obryn may be suggesting, each edition offers us a different kind of game play, and since we are all human we will not all agree on one version being the best game play for everyone.
So maybe people are "maturing" and finally realizing we should concentrate on what is fun, rather than getting all bent out of shape because someone else prefers an edition/version/clone of D&D you don't like.
Anyways, I hope this "trend" comes to represent the dominant attitude of ENWorld, I would like another board where I can find people with which I can discuss rules, etc... from every edition of D&D without people getting bent out of shape over a game.
I at least "like" every edition of D&D, and can and will playany of them. Heck, I even had a fun time playing Mythmere's S&W at a Convention a couple of weekends ago, a blast actually. I hope to be playing some 1E/LL/OSRIC in the near future, or some 2E, and I know I will be playing 4E again soon. A possible 3E game isn't on my radar yet, but hey, Gen Con is coming up with the intro of Pathfinder, so that can happen too. Plus I will certainly be running and playing C&C, CORTEX is lined up for next Monday, Traveller is coming up in a few weeks as well.
See the trend? I am a gamer, and I love to play. Hopefully everyone is realizing the same thing about themselves, and all the ugly arguments of the past will occur far less frequently now.
We are human, so I know they will not disappear.
