Because right now I could probably get $50 out of it, after buying it new for only $15.

If there is a port for PSP or a PS3 remake, the value will undoubtedly go down. Right now the only [legal] way to play it is on the PS1. If new ways are made available, then there are less chances I charge an arm and a leg for it over eBay.

So, we must do whatever it takes to prevent this game from rereleasing in any way!
