So anything in Dragon/Dungeon are official versions of DS for 3.5 and anything else is now strictly fan based. Official fansite is kind of misleading that way. You can ALWAYS be overruled by the folks with the copyright
Canon, shmanon. Use what you will and be damned with 'official' titles and such mularky. Its a game. More importantly, when at your own gaming table, its
your game. I don't care who puts it out, I just want more DS material than I can conceivably create on my own. I don't care if WOTC puts out the DS setting with pink muls in frilly satin shirts with SK DJ's spinning disco hits and the term 'defiling' has more of a taboo sexual innuendo. Official doesn't always mean good. Crap is still crap, even when trademarked. When in doubt, go with what appeals more, not what has a 'seal of approval'.
Besides, as I understand it, the only way for any of the fansites to be 'overuled' is if they were asked to shut down. WOTC isn't showing any signs of digging the dead settings from their graves, so there's no chance of any kind of overruling anyhow. The fansites aren't cutting into profits, and that's all that matters.
Personally, I dug Dark Sun, but the only people that I knew playing it were folks I didn't particularly enjoy gaming with (and, unfortunately, Dark Sun did little more than boost the behavior I didn't like)
Innitially, DS seemed to garner a lot of support from 'power-gamers' and munchkins. It took me almost a year to rework a decent group of gamers out of that mold and into a 'role' playing group. At least, that was the kind of turn-off behavior that I experienced from early fans of the setting.
Give me the stuff that REALLY matters and let ME worry about the rest.
Ahh, the root of the disagreement. I guess different things matter to different people. I already had tons of stats in 3e form for ships. If I wanted to zip them into space, I could have done that in far less than 50 pages. What matters to me then are the little things, the details. The fluff. The descriptions. The narratives. The setting. Give me something that I cannot create on my own at times - unique, derisive, and compelling avenues for the expression of my story. You can use crappy chunked up rules and still tell a good story and have a good game, but even the best game mechanics won't cover up for a flat, generic, lame setting. The SJ mini-game gave me some nice rules to use, but gave me a cruddy little lifeless and uninspiring setting to work with.
But, like I said, different things matter to different people. And in the end, my opinions mean absolutely zilch when you gather around your gaming table

Its still your game.
So the Aristolean physics refers to things falling faster if they're bigger and slower if they're smaller, or at least that's one angle of it all. So they updated the science of it all by oh...2500 or so years. Works for me.
It refers to the feel of the setting in general, that the fantastic is more probable than the realistic. When in doubt, go with the route of fantasy rather than the route of sensibility and real science. That was what was missing from the article.
