Well OP, it's time to stop thinkin' and start flippin'.
Seriously though, the way you feel about a game has no bearing on what a market dictates, obviously.
It's a really bad time to get into the SNES from scratch. It's a bad time buying games for any console really, but the SNES has become the worst.
Maybe it's because many of the kiddies who started with N64 since birth have realized it's a crumby system to collect for and have shifted their collector's mentality and money toward the SNES, on top of the fan base that never really went away to begin with. I don't know, it just seems like it's the "it" Nintendo system now.
I spent $80 on a loose Wild Guns at a FLEA MARKET almost three years ago. I felt like a total sucker. Not so much now.
EDIT: Actually, now that I think of it, I've over-paid for Hagane, Ninja Gaiden Trilogy, MMX3 etc. because deep down I knew that fabled day of "seein' it at da yardsale for $5" would never come like it supposedly has to many.
In retrospect, paying the prices I did wasn't a bad move at all.
