RPGs don't sell as well as the latest Call of Duty, so companies don't produce as many copies (lest they be stuck with the leftovers).JRPGs - buy a cheap Wii, and then get Xenoblade Chronicles, The Last Story and Pandora's Tower.
Damn limited runs. I really want Xenoblade Chronicles, but I am so not paying the $80+ that Ebay's asking for it. What is with the RPG genre and overpricing?
If you want more copies in the second-hand market, more people need to start buying them at release.
