Why are Harvest Moon games so expensive?

Well, i could not figure it. All the time. WHY? Snes game is very expensive, gb/gbc is among most expensive. psx is also expensive.

Its a great series. One of my favorites. The reason why the SNES and GB versions are pricey is because they had limited print runs. HM was not very popular when it came out. But due to many (great) sequels, it has become one of the more respected series in video games.

Also, the SNES version came out 1 year into the N64's release thus there were limited copies available. I remember being the only one who owned this game that I knew of and borrowed it to friends many times hehe.
