We seem to be moving into the subject of variants in general, rather than Aladdin's Dragons in particular. We are using the term "variant" very broadly. There's nothing wrong with that, but it would help me (and probably some others) to identify categories of variant.
First, there is the "fix." The cry goes up that a game is broken by a particular rule, card, spell, or whatever. If the cry goes up from a small group, with fewer than a dozen plays of the game between them, then I'd be sceptical.
But often the cry goes up from various points in a wider network. For example, when he makes the "stinky camel" objection to Al's Ds, Charles joins the ranks of Greg S. and others. I, on the other hand, agree with Dave that it's good to be da camel.
My preferred variant would be that highest bid for the camel space confers the right to *place* the camel. So if the turn order goes Charles, Andrew, Greg, Dave, then I would be hoping that Charles wins the camel bid and gives the beast to me. At the same time, each of Greg and Dave might be waiting for the other to bid, and to place it in front of Dave.
Another game that, it is said, needs fixing, is King of the Elves. Although I've only played it a couple of times, I can see the argument that a certain combination of cards breaks the game. I would rather play the game with a simple fix to this, although I'd happily agree to play without the fix; I would not be the first player to use the combination.
Then there is a point at which a game changes enough so that it is a more of a "descendant" of the original game than a variant of it. My game Spiel & Deal is, IMHO, in this category. It is a descendant of KK&K. KK&K is a business-themed board game with negotiation as the main mechanism. On the other hand, S&D has: game-playing as its theme; no board; and auctions as well as negotiation.
Talking of KK&K reminds me: did anyone ever answer my question about Saturday's KK&K. Was it an asterisk/variant game, or did "I'm the Boss" cards affect turn order?
I'll mention just one more category of variant: the "variant proper." There are many of these at, for example, http://www.io.com/~sos/gviews.html
Thanks to those who started this fascinating (to me) topic.
