Besides, I don't know if ebay/Amazon/ect prices are a particularly good indicator of rarity anymore. I mean hell I just bought Ike + Robin for under $30 NiB (including shipping) and they are about as rare as it gets. Shit, the Japanese versions of both are still up on Amazon for around $15 each. I guess the point is, as the collectors get their hands on these, even the "rare" ones will drop in price since demand will plummet.
That's very true. Inflated third party market prices don't exactly indicate rarity. I was just saying the current price isn't bad if you've got to have a Pit right now.
Demand is definitely affected by more than rarity. I went a long time without an Ike, because I wasn't as interested in him as a character. Still, I don't remember Ike ever being prohibitively expensive for me, unlike Marth, Lucina, and Robin.
I've noticed that Ike, Palutena, and Dark Pit haven't done as well as similar characters such as Lucina, Robin, Pit--even accounting for spikes and plummets in demand before, during, and after release.
Numerous factors determine the going third party market rate, but I'm thinking popularity is a major factor in the discrepancy between Ike and Robin/Lucina and between Pit and Palutena/Dark Pit. But there's the Age of the Amiibo Craze to consider too, which drove up ebay prices senselessly. I can't even.
