That's cool, but I still don't get why old dergs are popular? I honestly don't see the appeal? Is it just that they're old?
There are a couple reasons people have started liking old dragons, the most prevalent reason is probably that they're rare. There will never be any more old dragons than there are now. We judge "oldness" by the length of the ID number instead of strictly by age in months or years, which makes it easy to distinguish them from other dragons.
But yeah, the first 6 months or so I was on FR, old dragons wasn't even a thing yet. You could find 6 digit dragons for fodder prices and most of them were ugly and no one cared about them. After a while, people got the idea that old dragons were going "extinct".
In a way, people consider them the dragon equivalent of a retired item.
They're a part of the site's opening days, which also gives them a history. There are over 19,800,000 dragons on FR right now. We're closing in on 20mil fast. Imagine having a dragon that was one of the first 1000 on the site. It's survived aaaaaall the way since opening until now, without being exalted or abandoned on an account somewhere, which is kind of cool.
It's kind of like comparing rhinestones or glass crystals to diamonds? You might not be able to tell the difference at a glance, and they both serve the same purpose, but one is definitely rarer than the other, thus it's more sought after by some people who give value to that sort of thing. Of course, it's totally fine to not care about this side of FR, because breeding pretty dragons and buying the newest hatchlings with the newest genes is an enormous side of the site. I have my breeding dragons and my trophy dragons separate, to get the best of both worlds. xD;
I like old dragons partially because they're the next level of challenge for me. Pretty dragons are a dime a dozen in the AH, triple gened Imps and Coatls go for fodder price and get exalted all the time. Gen 1s are a pretty cool level of prestige, but people hatch eggs all the time, and numbers are only going up with the passage of time. Didn't win the auction for the G1 XXY with great colors? There'll probably be another one along sooner or later. But an old, low-digit dragon? There won't be more of those in the future. So it's fun for me to get an oldie and try to transform it into something that looks like the pretty dragons of the current market. I consider it to be "upgrading" my lair. Quality over quantity.
Mostly because in this game, you have to find something you enjoy working towards or else there's nothing to do. I guess this is my way of setting the next goal for myself.
That being said, if you find an ultra oldie in the AH by chance and don't care about keeping it, you should let me dump obscene quantities of internet dragon money on you in return for it. : D
